Abstract

According to one embodiment, a display device includes a first substrate having a first surface, a second surface opposite to the first surface and a first side surface, and a second substrate having a third surface opposed to the first surface, a fourth surface opposite to the third surface and a second side. The first substrate has a first inclined surface which is continuous with the first surface and the first side surface, the second substrate has a second inclined surface which is continuous with the fourth surface and the second side surface, and a first width of the first inclined surface is less than a second width of the second inclined surface.

Claims (39)

1. A display device comprising:

a first substrate having a first surface, a second surface and a first side surface, the first surface including a connection surface formed in a terminal portion, the second surface opposite to the first surface, the first side surface located between the first surface and the second surface; and

a second substrate having a third surface, a fourth surface and a second side surface, the third surface opposed to the first surface except for the connection surface, the fourth surface opposite to the third surface, the second side surface located between the third surface and the fourth surface, wherein

the first substrate has a first inclined surface which is continuous with the first surface and the first side surface in the terminal portion,

the second substrate has a second inclined surface which is continuous with the fourth surface and the second side surface at a position adjacent to the terminal portion, and

a first width of the first inclined surface is less than a second width of the second inclined surface.

2. The display device of claim 1 , further comprising:

a first side in a first direction;

a second side in a second direction which intersects the first direction; and

a curved corner located between the first side and the second side.

3. The display device of claim 2 , wherein the first inclined surface and the second inclined surface are located at the corner.

4. The display device of claim 2 , wherein

the first side surface is located between the first surface and the second surface across the first side, the second side and the corner, and

the second side surface is located between the third surface and the fourth surface across the second side and at least part of the corner.

5. The display device of claim 3 , wherein

the second substrate further has a third side surface which is elongated along the first side and is located between the third surface and the fourth surface,

the second inclined surface and the second side surface are continuous with the third side surface, and

the terminal portion extends outward beyond the third side surface.

6. The display device of claim 2 , wherein the first substrate further has a third inclined surface which is continuous with the second surface and the first side surface.

7. The display device of claim 6 , wherein a third width of the third inclined surface is equal to the second width.

8. The display device of claim 6 , wherein the third inclined surface is located throughout the entire corner.

9. The display device of claim 6 , wherein the first inclined surface and the third inclined surface are convex surfaces.

10. The display device of claim 9 , wherein a first radius of curvature of the first inclined surface is less than a second radius of curvature of the third inclined surface.

11. The display device of claim 1 , wherein

the second substrate has a third side surface which is elongated along the terminal portion and is located between the third surface and the fourth surface, and a fourth inclined surface which is located between the second side surface and the third side surface, and

the fourth inclined surface is a concave surface which is continuous with the third surface and the fourth surface.

12. The display device of claim 11 , wherein

the first inclined surface is a concave surface, and

a third radius of curvature of the first inclined surface and a fourth radius of curvature of the fourth inclined surface are equal to each other.

13. The display device of claim 12 , wherein a position of a center of curvature of the first inclined surface and a position of a center of curvature of the fourth inclined surface are equal to each other.

14. The display device of claim 1 , wherein

the second substrate has a third side surface which is elongated along the terminal portion and is located between the third surface and the fourth surface, and a fourth inclined surface which is located between the second side surface and the third side surface, and

the fourth inclined surface and the first inclined surface are flat surfaces.

15. The display device of claim 14 , wherein the fourth inclined surface and the first inclined surface are located on a same plane.

16. The display device of claim 2 , further comprising:

a display area;

a non-display area located outside the display area; and

a light-shielding layer arranged in the non-display area, wherein

a width of the light-shielding layer located between the display area and the terminal portion in the second direction is greater than a width of the light-shielding layer located between the display area and the second side in the first direction.
