Abstract

According to one embodiment, a display device includes first and second source lines arranged along a first direction, a gate line including first and second portions arranged along a second direction intersecting the first direction, and a connection portion which connects the first portion and the second portion to each other and a semiconductor layer which intersects at least one of the first portion and the connection portion, and each of the first portion and the second portion intersects the first and second source lines and the connection portion is located between the first source line and the second source line.

Claims (72)

1. A display device comprising:

first and second source lines arranged along a first direction;

a gate line including first and second portions which extend along the first direction and are arranged along a second direction intersecting the first direction, and a connection portion which connects the first portion and the second portion to each other; and

a semiconductor layer which intersects at least one of the first portion and the connection portion,

each of the first portion and the second portion intersecting the first and second source lines,

the connection portion being located between the first source line and the second source line, and

a width of the second portion in the second direction being greater than that of the first portion.

2. The display device of claim 1 , wherein

the width of the second portion is twice or more greater than that of the first portion.

3. The display device of claim 1 , wherein

the semiconductor layer intersects the first portion at two locations.

4. The display device of claim 3 , wherein

the semiconductor layer includes a first region extending along the second direction under the first source line and intersecting the first portion, a second region extending along the second direction from between the first source line and the connection portion and intersecting the first portion, and a third region connecting the first region and the second region to each other between the first portion and the second portion.

5. The display device of claim 4 , further comprising:

a pixel electrode,

wherein

the first region is electrically connected to the first source line, and

the second region is electrically connected to the pixel electrode between the first source line and the second source line.

6. A display device comprising:

first and second source lines arranged along a first direction;

a gate line including first and second portions which extend along the first direction and are arranged along a second direction intersecting the first direction, and a connection portion which connects the first portion and the second portion to each other; and

a semiconductor layer which intersects at least one of the first portion and the connection portion,

each of the first portion and the second portion intersecting the first and second source lines,

the connection portion being located between the first source line and the second source line, and

the semiconductor layer intersecting each of the first portion and the connection portion at one location.

7. The display device of claim 6 , wherein

the semiconductor layer includes a first region extending along the second direction under the first source line and intersecting the first portion and a second region connected to the first region, extending along the first direction between the first portion and the second portion and intersecting the connection portion.

8. The display device of claim 7 , further comprising:

a pixel electrode,

wherein

the first region is electrically connected to the first source line, and

the second region is electrically connected to the pixel electrode between the connection portion and the second source line.

9. A display device comprising:

first and second source lines arranged along a first direction;

a gate line including first and second portions which extend along the first direction and are arranged along a second direction intersecting the first direction, and a connection portion which connects the first portion and the second portion to each other; and

a semiconductor layer which intersects at least one of the first portion and the connection portion,

each of the first portion and the second portion intersecting the first and second source lines,

the connection portion being located between the first source line and the second source line, and

the semiconductor layer intersecting the connection portion at one location.

10. The display device of claim 9 , wherein

the semiconductor layer extends out along the first direction between the first portion and the second portion,

one end of the semiconductor layer is located under the first source line,

another end of the semiconductor layer is located between the second source line and the connection portion.

11. The display device of claim 10 , further comprising:

a pixel electrode,

wherein

the one end is electrically connected to the first source line, and

the another end is electrically connected to the pixel electrode.

12. A display device comprising:

first and second source lines arranged along a first direction;

a gate line including first and second portions which extend along the first direction and are arranged along a second direction intersecting the first direction, and a connection portion which connects the first portion and the second portion to each other;

a semiconductor layer which intersects at least one of the first portion and the connection portion; and

a first pixel electrode and a second pixel electrode adjacent to each other along the second direction between the first source line and the second source line,

each of the first portion and the second portion intersecting the first and second source lines,

the first portion and the second portion being located between the first pixel electrode and the second pixel electrode, and

the connection portion being located between the first source line and the second source line and between the first pixel electrode and the second pixel electrode.

13. The display device of claim 12 , wherein

an interval between the first portion and the second portion in the second direction is less than a length of the first pixel electrode.

14. A display device comprising:

first, second and third source lines arranged along a first direction; and

a gate line including first and second portions which extend along the first direction and are arranged along a second direction intersecting the first direction, and a first connection portion and a second connection portion which connect the first portion and the second portion to each other,

the first connection portion being located between the first source line and the second source line,

the second connection portion being located between the second source line and the third source line, and

a pitch of the first connection portion and the second connection portion being equal to that of the first source line and the second source line.

15. The display device of claim 14 , wherein

the gate line includes an opening elongated in the first direction between the first connection portion and the second connection portion.

16. The display device of claim 15 , wherein

a width of the opening in the second direction is greater than that of the first portion.

17. The display device of claim 15 , further comprising:

a semiconductor layer;

wherein

the semiconductor layer at least partially overlaps the opening.
