Abstract

Provided is a display device which includes an electrooptical panel and a protection member including a print part in a peripheral region and disposed to face the electrooptical panel to protect the electrooptical panel. The protection member includes a first reference mark in the peripheral region. The electrooptical panel includes a second reference mark in a position corresponding to the first reference mark and is held to have an overlap with the protection member. The print part includes at least the first print layer and a second print layer disposed in a position facing the first print layer. The first reference mark is made up of a hole having a predetermined shape formed in the second print layer.

Claims (25)

1. A display device, comprising:

an electrooptical panel; and

a protection member comprising a plate member, the protection member facing the electrooptical panel and covering at least a portion of the electrooptical panel, thereby protecting the electrooptical panel,

wherein

the protection member includes a first reference mark in a region peripheral to an array region of the electrooptical panel, and

the electrooptical panel overlaps with the protection member and includes a second reference mark in a position corresponding to the first reference mark, such that the first reference mark and the second reference mark at least partially overlap with each other.

2. The display device of claim 1 , wherein the protection member has a curved corner.

3. The display device of claim 1 , wherein the protection member has four curved corners.

4. The display device of claim 1 , wherein the first reference mark is at least partially cross shaped.

5. The display device of claim 4 , wherein the second reference mark is at least partially cross shaped.

6. The display device of claim 1 , wherein the first reference mark is selected from the group of circle shaped square shaped and triangular shaped.

7. The display device of claim 1 , wherein the first reference mark has a different color than a color of the second reference mark.

8. The display device of claim 1 , wherein the first reference mark at least partially overlaps the second reference mark in plan view.

9. The display device of claim 1 , wherein the first reference mark at least partially does not overlap the second reference mark in plan view.

10. The display device of claim 7 , wherein the first reference mark at least partially does not overlap the second reference mark in plan view.

11. The display device of claim 1 , wherein at least one of the first reference mark or the second reference mark is black.

12. The display device of claim 1 , wherein centers of the first reference mark and second reference mark coincide.

13. The display device of claim 2 , wherein the first and the second reference marks are at least partially cross shaped.

14. The display device of claim 2 , wherein the first reference mark is selected from the group of circle shaped, square shaped and triangular shaped.

15. The display device of claim 2 , wherein the first reference mark has a different color than a color of the second reference mark.

16. The display device of claim 2 , wherein the first reference mark at least partially overlaps the second reference mark in plan view.

17. The display device of claim 2 , wherein the first reference mark at least partially does not overlap the second reference mark in plan view.

18. The display device of claim 2 , wherein at least one of the first reference mark or the second reference mark is black.

19. The display device of claim 3 , wherein the first reference mark has a different color than a color of the second reference mark.

20. The display device of claim 15 , wherein the first reference mark at least partially does not overlap the second reference mark in plan view.
