Abstract

A display apparatus includes a display unit including a non-display region and a display region which extends from the non-display region in a direction defining an extension direction of the display region, and a supporting member on which the display unit is supported. The supporting member includes an intermediate mold including a first intermediate support disposed in the non-display region and an intermediate seat portion extending in the extension direction of the display region from the first intermediate support and disposed in the display region, and a transparent mold adjacent in the extension direction of the display region to the intermediate mold, between the intermediate seat portion and the display unit, and including a transparent support in an edge display region of the display region which is adjacent to the non-display region.

First claim

What is claimed is:

1. A display apparatus comprising:
a display unit comprising:
a non-display region, and
a display region extending from the non-display region in an extension direction, an edge display region of the display region being closest the non-display region;

an intermediate mold comprising:
a first intermediate support disposed under the non-display region to support the non-display region, and
an intermediate seat portion extending from the first intermediate support and disposed under the display region; and

a transparent mold disposed between the intermediate seat portion and the display region and comprising a transparent support in contact with the edge display region of the display region to support the edge display region.

2. The display apparatus of claim 1 , further comprising a diffusion plate,
wherein
the transparent mold further comprises a transparent seat portion which extends in the extension direction of the display region from an end of the transparent support, and
an end of the diffusion plate is disposed overlapping the transparent seat portion of the transparent mold.

3. The display apparatus of claim 2 , wherein
the display region of the display unit further comprises a central display region adjacent in the extension direction of the display region to the edge display region,
the transparent seat portion of the transparent mold is in the central display region, and
the end of the diffusion plate is disposed between the transparent seat portion and the display unit at the central display region thereof.

4. The display apparatus of claim 2 , wherein the transparent seat portion supports the diffusion plate.

5. The display apparatus of claim 2 , wherein the transparent seat portion of the transparent mold is disposed between the intermediate seat portion of the intermediate mold and the display unit.

6. The display apparatus of claim 2 , wherein the transparent support of the transparent mold is disposed between the diffusion plate and the first intermediate support of the intermediate mold in the extension direction of the display region.

7. The display unit of claim 2 , wherein
the display unit further comprises:
a display panel which generates an image and displays the image, and
an optical sheet which is disposed under the display panel, and

the first intermediate support of the intermediate mold and the transparent support of the transparent mold each contact a bottom surface of the optical sheet to support the bottom surface of the optical sheet.

8. The display apparatus of claim 7 , wherein a thickness of the transparent support of the transparent mold is greater than that of the diffusion plate, and a gap is defined between the bottom surface of the optical sheet and a top surface of the diffusion plate.

9. The display apparatus of claim 2 , wherein
the display unit further comprises a display panel which generates an image and displays the image, and
the first intermediate support of the intermediate mold and the transparent support of the transparent mold each contact a bottom surface of the display panel to support the bottom surface of the display panel.

10. The display apparatus of claim 9 , further comprising an optical sheet,
wherein the optical sheet is disposed on the diffusion plate, and a gap is defined between a top surface of the optical sheet and the bottom surface of the display panel.

11. The display apparatus of claim 1 , wherein
the first intermediate support of the intermediate mold and the transparent support of the transparent mold extend in a thickness direction of the display unit, and
the intermediate seat portion of the intermediate mold extends in the extension direction of the display region from a lower end of the first intermediate support and is parallel to the display unit.

12. The display apparatus of claim 11 , wherein the intermediate mold further comprises an inclined portion extending in the extension direction of the display region and inclinedly downward from a distal end of the intermediate seat portion.

13. The display apparatus of claim 1 , further comprising a diffusion plate,
wherein
an end of the diffusion plate is disposed between the intermediate seat portion of the intermediate mold and the display unit at the display region thereof, and
the end of the diffusion plate is spaced apart from the transparent support of the transparent mold in the extension direction of the display region.

14. The display apparatus of claim 13 , wherein the transparent support of the transparent mold is attached to a side surface of the first intermediate support of the intermediate mold.

15. The display apparatus of claim 1 , further comprising a light source which generates a light and provides the light to the display unit,
wherein the light source is disposed under the display region of the display unit and spaced apart from the intermediate mold in the extension direction of the display region to emit the light to a bottom surface of the display unit at the display region thereof.

16. The display apparatus of claim 15 , further comprising a bottom cover in which the light source is received,
wherein
the bottom cover comprises a bottom portion on which the intermediate mold and the light source are disposed, and a sidewall which extends from the bottom portion, and
the sidewall of the bottom cover is disposed between the first intermediate support of the intermediate mold and the bottom portion of the bottom cover to support the first intermediate support thereon.

17. The display apparatus of claim 1 , wherein
a side surface of the transparent mold is coupled to a facing side surface of the intermediate mold at a double injection-molded interface therebetween, and
an entirety of a bottom surface of the transparent mold contacts the intermediate mold.

18. A display apparatus comprising:
a display unit comprising a non-display region and a display region which extends from the non-display region in an extension direction;
an intermediate mold comprising:
a first intermediate support disposed under the non-display region to support the non-display region,
a second intermediate support adjacent in the extension direction of the display region to the first intermediate mold support in the non-display region of the display unit, and
an intermediate seat portion extending from the first intermediate support and disposed under the display region; and

a transparent mold disposed between the intermediate seat portion and the display region and comprising a transparent support configured to support an edge display region of the display region, which is adjacent to the non-display region,
wherein the second intermediate support is disposed in the edge display region of the display unit to support the edge display region.

19. The display apparatus of claim 18 , wherein a side surface of the second intermediate support of the intermediate mold contacts a side surface of the transparent support of the transparent mold.

20. A tiled display device comprising:
a display apparatus provided in plurality in a matrix form having M rows and N columns, wherein M and N are natural numbers,
each of the display apparatuses comprising:
a display unit comprising a non-display region and a display region which extends from the non-display region in at least one direction, an edge display region of the display region being closest the non-display region;
an intermediate mold comprising:
a first intermediate su
