Abstract

A display panel includes a lower panel configured to display an image. The lower panel includes a plurality of unit pixels. A slit layer is disposed on the lower panel. The slit layer includes a first pattern configured to form a first slit corresponding to each of the plurality of unit pixels and a second pattern configured to form a second slit corresponding to the first slit. The slit layer is configured to project an image through the first slit and the second slit. A top layer is disposed on the slit layer. The top layer is larger than the lower panel in a plan view. The top layer is configured to have the image projected thereon.

First claim

What is claimed is:

1. A display panel, comprising:
a lower panel configured to display an image, wherein the lower panel comprises a plurality of unit pixels;
a slit layer disposed on the lower panel, wherein the slit layer comprises a first pattern configured to form a first slit corresponding to each of the plurality of unit pixels and a second pattern configured to form a second slit corresponding to the first slit, and wherein the slit layer is configured to project an image through the first slit and the second slit; and
a top layer disposed on the slit layer, wherein the top layer is larger than the lower panel in a plan view, wherein the first pattern configured to form the first slit and the second pattern configured to form the second slit are spaced apart from the top layer, and wherein the top layer is configured to have the image projected thereon.

2. The display panel of claim 1 , wherein the lower panel further comprises a connecting terminal configured to receive a signal for driving the lower panel, wherein the connecting terminal is disposed on a peripheral area of the display panel, wherein the peripheral area is configured to not display the image, and wherein a boundary region of the top layer is configured to overlap the peripheral area of the lower panel.

3. The display panel of claim 2 , wherein at a central portion of the display panel, light of the image displayed on the lower panel is projected onto the top layer along a direction substantially perpendicular to a plane of the lower panel, and
wherein at the peripheral area of the display panel, the light of the image displayed on the lower panel is projected onto the top layer along an angle that is inclined with respect to the plane of the lower panel.

4. The display panel of claim 1 , wherein the slit layer comprises:
a first layer disposed on the lower panel between the lower panel and the first pattern;
a second layer disposed on the first layer between the first pattern and the second pattern; and
a third layer disposed on the second layer between the second pattern and the top layer, wherein the third layer separates the second pattern from the top layer, and
wherein the second layer has a different thickness from thicknesses of the first and third layers.

5. The display panel of claim 4 , wherein the first and second patterns are metal thin film patterns or printed ink patterns.

6. The display panel of claim 5 , wherein the first layer of the slit layer has a first thickness, the second layer has a second thickness, the third layer has a third thickness, and
a sum of the second thickness and the third thickness is larger than the first thickness.

7. The display panel of claim 1 , wherein the top layer comprises a translucent material.

8. The display panel of claim 1 , wherein the lower panel comprises a first substrate, a second substrate facing the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate, and
the second substrate comprises a second base substrate and a color filter disposed on the second base substrate.

9. The display panel of claim 8 , wherein the unit pixel comprises a first pixel, a second pixel and a third pixel,
a first color filter is disposed corresponding to the first pixel, a second color filter is disposed corresponding to the second pixel, a third color filter is disposed corresponding to the third pixel, and
the display panel is configured to display the image on the lower panel corresponding to the first to third pixels, and the display panel is configured to project the image through the first and second slits onto the top layer.

10. A display apparatus, comprising:
a display panel; and
a receiving container receiving the display panel,
wherein the display panel comprises:
a lower panel configured to display an image, and comprising a plurality of unit pixels;
a slit layer disposed on the lower panel, and comprising a first pattern configured to form a first slit corresponding to each of the plurality of unit pixels and a second pattern configured to form a second slit corresponding to the first slit; and
a top layer disposed on the slit layer on which the image through the slit layer is projected, wherein the first pattern configured to form the first slit and the second pattern configured to form the second slit are spaced apart from the top layer, and wherein the top layer is larger than the lower panel in a plan view, and

the receiving container comprises a bottom portion and a side wall extending from a boundary of the bottom portion, and
an outer surface of the side wall and a side surface of the top layer of the display panel are disposed in a same plane.

11. The display apparatus of claim 10 , further comprising an adhesive layer disposed between the receiving container and the display panel, wherein the adhesive layer is configured to attach the display panel to the receiving container.

12. The display apparatus of claim 10 , further comprising a protecting layer disposed on a side surface of the display panel, wherein the protecting layer is configure to block light and to protect the display panel.

13. The display apparatus of claim 12 , wherein the protecting layer comprises a black colored silicon.

14. The display apparatus of claim 10 , further comprising a driving part configured to drive the display panel, and
the lower panel of the display panel further comprises a connecting terminal disposed on a peripheral area of the display panel, wherein the peripheral area is disposed at a boundary of the display panel and the image is not displayed thereon, and
the driving part is electrically connected to the connecting terminal through a connecting part.

15. The display apparatus of claim 10 , wherein the slit layer comprises:
a first layer disposed on the lower panel between the lower panel and the first pattern;
a second layer disposed on the first layer between the first pattern and the second pattern; and
a third layer disposed on the second layer between the second pattern and the top layer, wherein the third layer separates the second pattern from the top layer, and
wherein the second layer has a different thickness from thicknesses of the first and third layers.

16. A method of manufacturing a display panel, comprising:
forming a lower panel for displaying an image;
forming a slit layer, for controlling a light path of the image, on the lower panel; and
forming a top layer, on which the image is projected, on the slit layer, the top layer being lager than the lower panel in a plan view,
wherein forming the slit layer comprises:
forming a first layer having a first thickness;
forming a first pattern having a first slit on the first layer;
forming a second layer having a second thickness on the first layer;
forming a second pattern having a second slit on second layer, the second slit being larger than the first slit, wherein the first pattern having the first slit and the second pattern having the second slit are spaced apart from the top layer; and
forming a third layer having a third thickness on the second pattern.

17. The method of claim 16 , wherein forming the first pattern comprises forming a metal layer on the first layer, and the first pattern is formed having the first slit by patterning the metal layer.
