Abstract

A window member includes a base substrate including a bottom surface, an upper surface opposed to the bottom surface, and a connecting surface between the bottom surface and the upper surface, and a blocking layer on the connecting surface, the blocking layer including an ultraviolet absorber.

Claims (48)

1. A window member, comprising:

a base substrate including a bottom surface, an upper surface opposed to the bottom surface, and a connecting surface between the bottom surface and the upper surface;

a blocking layer on the connecting surface and exposing a majority of each of the bottom surface and the upper surface, the blocking layer including an ultraviolet absorber; and

a light blocking layer on the bottom surface, the light blocking layer being different from the blocking layer,

wherein the blocking layer extends on a portion of the at least one surface of the upper surface or the bottom surface, and

wherein the blocking layer has a higher transparency than the light blocking layer.

2. The window member as claimed in claim 1 , wherein the ultraviolet absorber includes a benzotriazol, benzophenone, salicylic acid, salicylate, cyanoacrylate, cinnamate, oxanilide, polystyrene, azomethine, or triazine-based compound, or a combination thereof.

3. The window member as claimed in claim 1 , wherein the blocking layer absorbs light having a wavelength range of 300 nm to 400 nm inclusive.

4. The window member as claimed in claim 1 , wherein the connecting surface includes at least one curved portion.

5. The window member as claimed in claim 1 , wherein the blocking layer further includes at least one of silica or titanium dioxide (TiO 2 ).

6. The window member as claimed in claim 1 , wherein the blocking layer is a transparent layer.

7. The window member as claimed in claim 1 , wherein the light blocking layer is a black printed layer or white printed layer.

8. The window member as claimed in claim 1 , wherein the connecting surface includes:

a first sub connecting surface connected to the bottom surface, the first sub connecting surface having a first curvature; and

a second sub connecting surface disposed between the first sub connecting surface and the upper surface, the second sub connecting surface having a second curvature.

9. The window member as claimed in claim 8 , wherein the blocking layer is on the first sub connecting surface.

10. The window member as claimed in claim 8 , wherein the first and second curvatures are different from each other.

11. The window member as claimed in claim 8 , wherein the second curvature is greater than the first curvature.

12. The window member as claimed in claim 8 , wherein the connecting surface further includes a third sub connecting surface between the first and second sub connecting surfaces.

13. The window member as claimed in claim 1 , wherein the light blocking layer is at an edge of the bottom surface.

14. The window member as claimed in claim 13 , wherein the blocking layer neighbors one side surface of the light blocking layer.

15. A display device, comprising:

a display panel;

a window member on the display panel; and

an adhesive member between the display panel and the window member, wherein the window member includes

a base substrate including a bottom surface facing the display panel, an upper surface opposed to the bottom surface, and a connecting surface between the bottom surface and the upper surface, and

a blocking layer directly on the connecting surface and exposing a majority of the upper surface, the blocking layer including an ultraviolet absorber.

16. The display device as claimed in claim 15 , wherein the ultraviolet absorber comprises a benzotriazol, benzophenone, salicylic acid, salicylate, cyanoacrylate, cinnamate, oxanilide, polystyrene, azomethine, or a triazine-based compound, or a combination thereof.

17. The display device as claimed in claim 15 , wherein the blocking layer absorbs light having a wavelength range of 300 nm to 400 nm inclusive.

18. The display device as claimed in claim 15 , wherein the blocking layer further comprises at least one of silica or titanium dioxide (TiO 2 ).

19. The display device as claimed in claim 15 , wherein the adhesive member is adhered to at least one of the bottom surface of the base substrate or a surface of a light blocking layer located on the bottom surface of the base substrate.

20. A display device, comprising:

a display panel;

a window member on the display panel; and

an adhesive member between the display panel and the window member, wherein the window member includes:

a base substrate including a bottom surface facing the display panel, an upper surface opposed to the bottom surface, and a connecting surface between the bottom surface and the upper surface,

a blocking layer on the connecting surface and exposing a majority of the upper surface, the blocking layer including an ultraviolet absorber, and

a light blocking layer on an edge region of the bottom surface.

21. The display device as claimed in claim 20 , wherein the blocking layer neighbors one side surface of the light blocking layer.

22. A display device, comprising:

a display panel;

a window member on the display panel; and

an adhesive member between the display panel and the window member,

an optical member between the display panel and the adhesive member, wherein

the adhesive member surrounds a side surface of the optical member, and

the window member includes:

a base substrate including a bottom surface facing the display panel, an upper surface opposed to the bottom surface, and a connecting surface between the bottom surface and the upper surface, and

a blocking layer on the connecting surface and exposing a majority of the upper surface, the blocking layer including an ultraviolet absorber.
