Abstract

A window for a display device that includes: a base substrate; a first coating layer disposed on a first surface of the base substrate; and a second coating layer disposed on a second surface that overlaps the first surface of the base substrate, wherein the base substrate further includes a vertical surface perpendicular to the first surface and the second surface, and the first coating layer overlaps the vertical surface. The impact resistance of the window is improved through the first coating layer covering the rear surface and the vertical surface of the base substrate.

Claims (29)

1 . A window for a display device, comprising:

a base substrate comprising a first surface, a second surface opposite the first surface, a first inclined surface that is inclined with respect to the first surface, and a second inclined surface that is inclined with respect to the second surface,

a first coating layer disposed directly on a first surface of the base substrate and configured for securing the base substrate to the display device,

wherein:

the first coating layer directly overlaps the first inclined surface and the second inclined surface; and

the first coating layer comprises methyl T polydimethylsiloxane.

2 . The display device of claim 1 , wherein the base substrate further comprises a vertical surface perpendicular to the first surface and the second surface, and the first coating layer directly overlaps the vertical surface.

3 . The display device of claim 2 , wherein the first inclined surface connects the first surface and the vertical surface.

4 . The display device of claim 2 , wherein the second inclined surface connects the second surface and the vertical surface.

5 . The display device of claim 1 , wherein the base substrate and the first coating layer are covalently bonded to each other.

6 . The display device of claim 1 , wherein a first surface of the base substrate comprises a groove, and the first coating layer fills the groove.

7 . The display device of claim 1 , wherein the second surface dose not directly contact the first coating layer.

8 . A display device, comprising:

a display panel; and

a window configured to cover the display panel,

wherein:

the window comprises:

a base substrate comprising a first surface, a second surface opposite the first surface, a first inclined surface that is inclined with respect to the first surface, and a second inclined surface that is inclined with respect to the second surface; and

a first coating layer disposed directly on a first surface of the base substrate and configured for securing the base substrate to the display device;

the first coating layer directly overlaps the first inclined surface and the second inclined surface; and

the first coating layer comprises methyl T polydimethylsiloxane.

9 . The display device of claim 8 , wherein the base substrate further comprises a vertical surface perpendicular to the first surface and the second surface, and the first coating layer directly overlaps the vertical surface.

10 . The display device of claim 9 , wherein the first inclined surface connects the first surface and the vertical surface.

11 . The display device of claim 9 , wherein the second inclined surface connects the second surface and the vertical surface.

12 . The display device of claim 8 , wherein the base substrate and the first coating layer are covalently bonded to each other.

13 . The display device of claim 8 , wherein a first surface of the base substrate comprises a groove, and the first coating layer fills the groove.

14 . The display device of claim 8 , wherein the second surface dose not directly contact the first coating layer.

15 . The display device of claim 8 , further comprising an adhesive layer and a light blocking layer disposed between the first coating layer and the display panel.

16 . The display device of claim 8 , wherein the first coating layer further comprises at least one of octamethylcyclotetrasiloxane and dimethylsiloxane.
