Display device
View Patent ↗According to one embodiment, there is provided a display device which includes an insulating substrate having a bend area, and a wiring line located in the bend area. The bend area is bent about a bend axis extending in a first direction. The wiring line in the bend area has a first portion which extends in the first direction and a second portion which extends in a direction intersecting the first portion and is connected to the first portion. A first angle formed by the first portion and the second portion is less than 90 degrees.
1. A display device comprising:
an insulating substrate having a bend area; and
a wiring line located in the bend area, wherein
the bend area is bent about a bend axis extending in a first direction,
the wiring line in the bend area has a first portion which extends in the first direction and a second portion which extends in a direction intersecting the first portion and is connected to the first portion,
a first angle formed by the first portion and the second portion is less than 90 degrees, and
the wiring line has a third portion which is arranged with the second portion in the first direction and is connected to the first portion.
2. The display device of claim 1 , wherein the third portion is connected to the second portion.
3. The display device of claim 1 , wherein the third portion extends parallel to the second portion.
4. The display device of claim 1 , wherein a first width of the first portion is less than a second width of the second portion.
5. The display device of claim 1 , further comprising a first inorganic insulating layer located between the wiring line and the insulating substrate.
6. The display device of claim 5 , wherein
the first inorganic insulating layer has a fourth portion which overlaps the second portion, and
a second angle formed by the first portion and the fourth portion is less than the first angle.
7. The display device of claim 6 , wherein a third width of the fourth portion is greater than a second width of the second portion.
8. The display device of claim 7 , wherein the first inorganic insulating layer has
a fifth portion which overlaps the first portion, and
a fourth width of the fifth portion is less than the third width.
9. The display device of claim 5 , further comprising a second inorganic insulating layer which covers the wiring line and contacts the first inorganic insulating layer.
10. The display device of claim 1 , further comprising a resin layer which covers the wiring line, wherein
the resin layer contacts the insulating substrate on both sides of the wiring line.
11. The display device of claim 1 , wherein the insulating substrate is formed of an organic material.
12. A display device comprising:
an insulating substrate having a bend area;
a wiring line located in the bend area; and
a first inorganic insulating layer located between the wiring line and the insulating substrate, wherein
the bend area is bent about a bend axis extending in a first direction,
the wiring line has a first bend portion which is bent at a first bend angle in the bend area,
the first inorganic insulating layer has a second bend portion which overlaps the first bend portion and is bent at a second bend angle,
the first bend angle and the second bend angle are less than 180 degrees, and
the second bend angle is less than the first bend angle.
13. The display device of claim 12 , wherein
the wiring line has a third bend portion which is arranged with the first bend portion in the first direction, and a first connecting portion which connects the first bend portion and the third bend portion,
the first inorganic insulating layer has a fourth bend portion which is arranged with the second bend portion in the first direction, and a second connecting portion which connects the second bend portion and the fourth bend portion, and
the first connecting portion and the second connecting portion extend in the first direction.
