Abstract

A display device includes a first substrate that is provided with a display element in a display region, a second substrate that faces the first substrate, and a sealant that bonds the first substrate and the second substrate to each other in a region surrounding the periphery of the display region in a plan view, in which each of the first substrate and the second substrate has a rectangular shape, in which at least one of the first substrate and the second substrate has a corner portion and a recess formed at a position which is close to the corner portion and overlaps at least a part of the region in which the sealant is disposed, and in which the sealant is provided to be in contact with at least a surface far from the display region among inner surfaces of the recess.

Claims (46)

1. A display device comprising:

a first substrate that is provided with a display element in a display region;

a second substrate that faces the first substrate and is disposed on a side of the first substrate where the display element is provided; and

a sealant that bonds the first substrate and the second substrate to each other in a region surrounding the periphery of the display region in a plan view,

wherein each of the first substrate and the second substrate has a rectangular shape,

wherein at least one of the first substrate and the second substrate has a plurality of first corner portions and a plurality of the recesses which are respectively close to the plurality of first corner portions and overlap at least a part of the region in which the sealant is disposed,

wherein each of the recesses is not connected to the other recesses,

wherein each of recesses has a second corner portion which is close to one of the first corner portions,

wherein each of the recesses has a first inner wall extending from the second corner portion, the inner wall is parallel to one edge of the first substrate,

wherein each of the recesses has a second inner wall extending from an end of the first inner wall,

wherein the sealant gets over the second inner wall, and extends in a first direction outside each of the recesses,

wherein a distance from the second corner portion to an inner side of the sealant is greater than the width of the sealant in a second direction orthogonal to the first direction, and

wherein the sealant is provided to be in contact with at least a surface far from the display region among inner surfaces of the recess.

2. The display device according to claim 1 ,

wherein the recess surrounds the entire periphery of the display region in a plan view.

3. The display device according to claim 1 ,

wherein the at least one of the first substrate and the second substrate is a glass substrate.

4. The display device according to claim 1 ,

wherein the at least one of the first substrate and the second substrate is a resin substrate.

5. The display device according to claim 1 ,

wherein the sealant is separated from at least a portion of a surface close to the display region among the inner surfaces of the recess.

6. The display device according to claim 1 ,

wherein the recess is provided to overlap the entire region where the sealant is disposed in a plan view.

7. The display device according to claim 1 ,

wherein each of the first substrate and the second substrate has a rectangular shape, and the first substrate has a protrusion protruding from the second substrate.

8. A display device comprising:

a first substrate that has a display region in which a plurality of display elements are disposed, and a peripheral region surrounding the display region;

a second substrate that faces the first substrate; and

a sealant that is interposed between the first substrate and the second substrate, and is located in the peripheral region,

wherein the peripheral region includes a first region which is close to an end of the first substrate and in which a thickness of the first substrate is a first thickness; a second region which is located between the first region and the display region and in which a thickness of the first substrate is a second thickness; and a third region which is located between the second region and the display region and in which a thickness of the first substrate is a third thickness,

wherein each of the first thickness and the third thickness is larger than the second thickness thereby forming a recess having a bottom on the second region,

wherein the sealant includes a first sealant extending in a first direction and a second sealant extending in a second direction intersecting the first direction,

wherein an intersection where the first sealant and the second sealant intersect each other is located in a region overlapping the second region in a plan view, and

wherein a first distance in at least one direction of the first direction and the second direction between one of a plurality of edges of the first substrate and an inner side of the sealant in the intersection is greater than a second distance in the at least one direction between the one edge of the first substrate and the inner side of the sealant outside of the second region.

9. The display device according to claim 8 ,

wherein the sealant is continuously disposed in the peripheral region along an outer edge of the second substrate in a plan view.

10. The display device according to claim 8 ,

wherein the recess surrounds the entire periphery of the display region in a plan view.

11. The display device according to claim 8 ,

wherein the at least one of the first substrate and the second substrate is a glass substrate.

12. The display device according to claim 8 ,

wherein the at least one of the first substrate and the second substrate is a resin substrate.

13. The display device according to claim 8 ,

wherein the sealant is separated from at least a surface close to the display region among the inner surfaces of the recess.

14. The display device according to claim 8 ,

wherein each of the first substrate and the second substrate has a rectangular shape, the first substrate has a protrusion protruding from the second substrate.
