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.
