Abstract

A display device includes a window and a display panel coupled to a bottom surface of the window. The display panel has a substantially regular tetragonal shape or a substantially rectangular shape in a plan view, and the window includes a base member and a bezel layer on a bottom surface of the base member. Between one and three light-transmissive main alignment marks and a transmission area having a different shape than that of the display panel are defined in the bezel layer, and each of the main alignment marks is arranged at a position corresponding to a vertex of the display panel or at a position corresponding to a vertex of an imaginary regular tetragon or of an imaginary rectangle that has the same center point as the display panel and that is larger than the display panel.

First claim

What is claimed is:

1. A display device comprising:
a window; and
a display panel coupled to a bottom surface of the window and having a substantially regular tetragonal shape or a substantially rectangular shape in a plan view,
wherein the window comprises:
a base member; and
a bezel layer on a bottom surface of the base member, at least one light-transmissive main alignment mark and a transmission area having a different shape than that of the display panel being defined in the bezel layer, and

wherein the at least one light-transmissive main alignment mark is arranged at a position overlapping a vertex of the display panel or at a position overlapping a vertex of an imaginary regular tetragon or of an imaginary rectangle that has the same center point as the display panel and that is larger than the display panel.

2. The display device of claim 1 , wherein the at least one light-transmissive main alignment mark comprises two light-transmissive main alignment marks, and
the two light-transmissive main alignment marks are arranged at positions overlapping corresponding to two vertices corresponding to one side edge of the display panel.

3. The display device of claim 2 , wherein each of the two light-transmissive main alignment marks overlaps a vertex of the display panel.

4. The display device of claim 1 , further comprising a light-transmissive sub-alignment mark defined in the bezel layer, spaced from the at least one light-transmissive main alignment mark, and having a different size than that of the at least one light-transmissive main alignment mark.

5. The display device of claim 4 , wherein the light-transmissive sub-alignment mark overlaps an edge of the display panel.

6. The display device of claim 1 , further comprising a light-transmissive test mark defined in the bezel layer and arranged outside of the display panel.

7. The display device of claim 6 , wherein the light-transmissive test mark has a different shape than that of the at least one light-transmissive main alignment mark.

8. The display device of claim 1 , wherein a corner area of the display panel has a curved line shape in a plan view.

9. The display device of claim 1 , wherein the display device is installed in a vehicle.

10. The display device of claim 9 , wherein the transmission area is exposed from an interior material of the vehicle,
wherein the interior material of the vehicle covers a portion of the bezel layer, and
wherein the at least one light-transmissive main alignment mark overlaps the interior material of the vehicle.

11. A display device comprising:
a window; and
a display panel coupled to a bottom surface of the window and having:
a display area having a substantially regular tetragonal shape or a substantially rectangular shape in a plan view; and
a non-display area outside of the display area,

wherein the window comprises:
a base member; and
a bezel layer on a bottom surface of the base member,

wherein at least one light-transmissive main alignment mark is defined in the bezel layer and a transmission area having a different shape than that of the display area is defined in the bezel layer, and
wherein the at least one light-transmissive main alignment mark is arranged at a position overlapping a vertex of the display area or at a position overlapping a vertex of an imaginary regular tetragon or an imaginary rectangle that has the same center point as the display area and is larger than the display area.

12. The display device of claim 11 , wherein the display panel has a different shape than that of the display area in a plan view.

13. The display device of claim 11 , wherein the display panel has a substantially regular tetragonal shape or a substantially rectangular shape in a plan view.

14. The display device of claim 13 , wherein the at least one light-transmissive main alignment mark is arranged at a position corresponding to a vertex of the display panel.

15. The display device of claim 11 , wherein a corner area of the display area has a curved line shape in a plan view.

16. A display device comprising:
a window; and
a display panel coupled to a bottom surface of the window and having a regular tetragonal shape with a curved corner area in a plan view or a rectangular shape with a curved corner area in a plan view,
wherein the window comprises:
a base member; and
a bezel layer on a bottom surface of the base member and having at least one light-transmissive main alignment mark and a transmission area,

wherein the transmission area has a different shape than that of the display panel, and
wherein the at least one light-transmissive main alignment mark is arranged at a position overlapping a vertex of the display panel or at a position overlapping a vertex of an imaginary regular tetragon or an imaginary rectangle that has the same center point as the display panel and that is larger than the display panel.

17. A display device comprising:
a window; and
a display panel coupled to a bottom surface of the window and having a substantially regular polygonal shape having n edges in a plan view,
wherein the window comprises:
a base member; and
a bezel layer on a bottom surface of the base member, a number of light-transmissive alignment marks being defined in the bezel layer and a transmission area having a different shape than that of the display panel being defined in the bezel layer,

wherein the number of the alignment marks is n−i, where “i” is a natural number equal to or greater than one and less than “n”, and
wherein each of the alignment marks is arranged at a position overlapping a vertex of the display panel or at a position overlapping a vertex of an imaginary polygon that has the same center point as the display panel and that is larger than the display panel.
