Abstract

A display panel includes a first substrate defining a display area thereof in which an image is displayed and a pad area thereof which is disposed extended from an edge of the display area and in which the image is not displayed; a second substrate disposed overlapping the display area of the first substrate; a spacer disposed on the pad area of the first substrate; and an upper polarizing plate disposed on the second substrate, the upper polarizing plate extended further than the second substrate to be disposed on the spacer on the pad area of the first substrate The spacer includes a body portion and a light-blocking layer which is disposed on a surface of the body portion.

First claim

What is claimed is:

1. A display panel comprising:
a first substrate defining a display area thereof in which an image is displayed and a pad area thereof which is disposed extended from an edge of the display area and in which the image is not displayed;
a second substrate disposed overlapping the display area of the first substrate;
a spacer disposed on the pad area of the first substrate; and
an upper polarizing plate disposed on the second substrate, the upper polarizing plate extended further than the second substrate to be disposed on the spacer on the pad area of the first substrate,
wherein the spacer comprises a body portion and a light-blocking layer which is disposed on a surface of the body portion.

2. The display panel of claim 1 , wherein the light-blocking layer is disposed between the first substrate and the body portion.

3. The display panel of claim 1 , wherein the light-blocking layer is disposed between the body portion and the upper polarizing plate.

4. The display panel of claim 1 , wherein the body portion comprises a tempered glass or polymer resin.

5. The display panel of claim 1 , further comprising a conductive coating layer disposed between the first substrate and the spacer.

6. The display panel of claim 1 , further comprising an adhesion member disposed between the first substrate and the spacer.

7. The display panel of claim 1 , further comprising:
a plurality of pads which is disposed in the pad area of the first substrate and provides driving signals to the display area of the first substrate to drive the display area, and
a flexible printed circuit board which is connected to the plurality of pads and provides the driving signals to the plurality of pads.

8. The display panel of claim 1 , further comprising a light blocking member disposed on an edge of the second substrate, the edge of the second substrate adjacent to the pad area of the first substrate.

9. The display panel of claim 1 , wherein a height defined from the first substrate to a top surface of the second substrate overlapping the display area of the first substrate is substantially the same as that from the first substrate to a top surface of the spacer on the pad area of the first substrate.

10. The display panel of claim 1 , wherein the spacer on the pad area of the first substrate contacts the second substrate overlapping the display area of the first substrate.

11. The display panel of claim 1 , further comprising a liquid crystal layer disposed between the first substrate and the second substrate.

12. The display panel of claim 1 , further comprising a lower polarizing plate disposed on a rear surface of the first substrate.

13. A display device comprising:
a display panel configured to display an image; and
a frame configured to overlap an edge of a rear surface of the display panel to support the display panel thereon,
wherein the display panel comprises:
a first substrate defining a display area thereof in which the image is displayed and a pad area thereof which is disposed adjacent to an edge of the display area and in which the image is not displayed;
a second substrate disposed overlapping the display area of the first substrate;
a spacer disposed on the pad area of the first substrate; and
an upper polarizing plate disposed on the second substrate, the upper polarizing plate extended further than the second substrate to be disposed on the spacer on the pad area of the first substrate,
wherein the spacer comprises a body portion and a light-blocking layer disposed on a surface of the body portion.

14. The display device of claim 13 , wherein the light-blocking layer is disposed between the first substrate and the body portion.

15. The display device of claim 13 , wherein the light-blocking layer is disposed between the body portion and the upper polarizing plate.

16. The display device of claim 13 , wherein the body portion comprises a tempered glass or polymer resin.

17. The display device of claim 13 , further comprising a conductive coating layer disposed between the first substrate and the spacer.

18. The display device of claim 13 , further comprising a light blocking member disposed on an edge of the second substrate, the edge of the second substrate adjacent to the pad area of the first substrate.

19. The display device of claim 13 , wherein a height defined from the first substrate to a top surface of the second substrate overlapping the display area of the first substrate is substantially the same as that from the first substrate to a top surface of the spacer on the pad area of the first substrate.

20. The display device of claim 13 , wherein the spacer on the pad area of the first substrate contacts the second substrate overlapping the display area of the first substrate.

21. A display panel comprising:
a first substrate defining a display area thereof in which an image is displayed and a non-display area thereof which extends from an edge of the display area and in which the image is not displayed;
a second substrate disposed overlapping the display area of the first substrate;
a spacer disposed on the non-display area of the first substrate; and
a polarizing plate disposed on the second substrate, the polarizing plate extended further than the second substrate to be attached to the spacer on the non-display area of the first substrate,
wherein the spacer comprises a body portion and a light-blocking layer which is disposed on a surface of the body portion.

22. The display panel of claim 21 , wherein
the non-display area of the first substrate further defines a pad area of the first substrate, the pad area lengthwise extending in a first direction.

23. The display panel of claim 22 , wherein
the non-display area comprises a first curved surface of the first substrate;
the spacer further comprises a second curved surface thereof corresponding to the first curved surface of the first substrate, and
the second curved surface is bent with respect to a bending axis that is lengthwise parallel to the first direction.

24. The display panel of claim 21 , wherein the light-blocking layer is disposed between the body portion and the polarizing plate.

25. The display panel of claim 21 , wherein the body portion is disposed between the light-blocking layer and the polarizing plate.
