Abstract

A display device include a display panel with first and second substrates facing each other, a window part provided on the display panel and including a light-blocking region provided at an edge region thereof, an adhesive part provided between the display panel and the window part, and a plurality of optical patterns provided on an edge region of a bottom surface of the first substrate.

First claim

What is claimed is:

1. A display device, comprising:
a display panel comprising first and second substrates which face each other;
a window part disposed on the display panel and which comprises a light-blocking region disposed at an edge region thereof;
an adhesive part disposed between the display panel and the window part; and
a plurality of optical patterns disposed on an edge region of a bottom surface of the first substrate,
wherein the optical patterns are recess patterns which are defined in the bottom surface of the substrate or protruding patterns which protrude from the bottom surface of the first substrate.

2. The display device of claim 1 , wherein the optical patterns are disposed on a region corresponding to the light-blocking region.

3. The display device of claim 2 , wherein the optical patterns are disposed to overlap the adhesive part along a thickness direction of the adhesive part.

4. The display device of claim 1 , wherein the display panel comprises a display area and a non-display area adjacent to the display area, and
the optical patterns are disposed on a region corresponding to the non-display area.

5. The display device of claim 1 , wherein the recess patterns are filled with an optical resin whose refractive index is different from that of the first substrate.

6. The display device of claim 5 , wherein the optical resin further comprises at least one of a TiO 2 particle or a SiO 2 particle.

7. The display device of claim 1 , wherein the protruding patterns and the first substrate are a single body.

8. The display device of claim 1 , wherein the protruding patterns comprises an optical resin whose refractive index is different from that of the first substrate.

9. The display device of claim 8 , wherein the optical resin further comprises at least one of a TiO 2 particle or a SiO 2 particle.

10. The display device of claim 1 , further comprising a touch sensing unit provided between the display panel and the adhesive part.

11. The display device of claim 1 , wherein the display panel comprises a liquid crystal display panel including a liquid crystal layer disposed between the first and second substrates.

12. The display device of claim 1 , wherein the display panel is an organic light emitting display panel, and
the first substrate is an encapsulation substrate.

13. A display device, comprising:
a display panel comprising first and second substrates which face each other;
a window part disposed on the display panel and which comprises a light-blocking region disposed at an edge region thereof;
an adhesive part disposed between the display panel and the window part; and a plurality of optical patterns disposed on an edge region of a bottom surface of the first substrate,

wherein each of the optical patterns has at least one of semi-circular, semi-elliptical, or polygonal shapes, on a plane normal to the bottom surface of the first substrate.

14. The display device of claim 13 , wherein the optical patterns are disposed on a region corresponding to the light-blocking region.

15. The display device of claim 13 , wherein the display panel comprises a display area and a non-display area adjacent to the display area, and
the optical patterns are disposed on a region corresponding to the non-display area.

16. A display device, comprising:
a display panel comprising first and second substrates which face each other;
a window part disposed on the display panel and which comprises a light-blocking region disposed at an edge region thereof;
an adhesive part disposed between the display panel and the window part; and a plurality of optical patterns disposed on an edge region of a bottom surface of the first substrate,

wherein the first substrate comprises at least one of first and second inclined surfaces, which are respectively defined near corners of a top surface and the bottom surface of the first substrate.

17. The display device of claim 16 , wherein the first inclined surface is inclined at an angle of 120 to 150 degrees, relative to the top surface of the first substrate.

18. The display device of claim 16 , wherein the second inclined surface is inclined at an angle of 30 to 60 degrees, relative to the top surface of the first substrate.

19. The display device of claim 16 , wherein the optical patterns are disposed on a region corresponding to the light-blocking region.

20. The display device of claim 16 , wherein the display panel comprises a display area and a non-display area adjacent to the display area, and
the optical patterns are disposed on a region corresponding to the non-display area.
