Abstract

According to one embodiment, a display device includes a first substrate including a display area, a terminal area, a first side and a third side, and a second substrate opposed to the first substrate and including a fifth side and a seventh side. The terminal area is sandwiched between the third side and the seventh side. The first substrate includes a first round corner between the first side and the third side. The second substrate includes a third round corner between the fifth side and the seventh side. A radius of curvature of the third round corner is smaller than a radius of curvature of the first round corner.

Claims (25)

1. A substrate comprising:

a basement;

a color filter; and

a light-shielding layer between the basement and the color filter,

wherein

the basement includes a first edge portion extending in a first direction, a second edge portion parallel to the first edge portion, a third edge portion extending in a second direction intersecting the first direction, a first corner portion between the first edge portion and the third edge portion, and a second corner portion between the second edge portion and the third edge portion,

a first radius of curvature of the first corner portion is different from a second radius of curvature of the second corner portion, and

an edge of the light-shielding layer overlaps the first corner portion and the second corner portion.

2. The substrate of claim 1 , wherein

the first radius of curvature is larger than the second radius of curvature.

3. The substrate of claim 2 , wherein

the light-shielding layer has a frame shape and is provided in a peripheral area outside a display area, and

a first width of the light-shielding layer between the display area and the first edge portion in the second direction is smaller than a second width between the display area and the second edge portion in the second direction.

4. The substrate of claim 2 , wherein

the light-shielding layer has a frame shape and is provided in a peripheral area outside a display area,

the display area has a third corner portion along the first corner portion and a fourth corner portion along the second corner portion, and

a third radius of curvature of the third corner portion is same as a fourth radius of curvature of the fourth corner portion.

5. The substrate of claim 4 , wherein

the first radius of curvature is larger than the third radius of curvature, and

the second radius of curvature is smaller than the fourth radius of curvature.

6. The substrate of claim 2 , wherein

the light-shielding layer has a frame shape and is provided in a peripheral area outside a display area, and

a third width of the light-shielding layer between the display area and the third edge portion in the first direction is smaller than a second width between the display area and the second edge portion in the second direction.

7. The substrate of claim 1 , wherein

each of the first edge portion, the second edge portion, and the third edge portion is a linear portion.
