Abstract

A display device of an embodiment includes scanning lines, signal lines, sub-pixels, a switching element in each of the sub-pixels, a pixel electrode in each of the sub-pixels. The switching element includes a relay electrode in contact with the pixel electrode, and a semiconductor layer in contact with the signal line in a first position, in contact with the relay electrode in a second position, and bending between the first position and the second position and crossing the scanning line. In at least one of the sub-pixels, a part of the scanning line extends between the relay electrode and the signal line which are connected to each other via the semiconductor layer.

Claims (39)

1. A display device comprising:

scanning lines;

signal lines crossing the scanning lines;

sub-pixels defined by the scanning lines and the signal lines;

a switching element in each of the sub-pixels;

a pixel electrode in each of the sub-pixels, wherein

the switching element includes:

a relay electrode in contact with the pixel electrode; and

a semiconductor layer in contact with the signal line in a first position, in contact with the relay electrode in a second position, and bending between the first position and the second position and crossing the scanning line, and

in at least one of the sub-pixels, a part of the scanning line extends between the relay electrode and the signal line which are connected to each other via the semiconductor layer, wherein

the scanning line includes a projection in at least one of the sub-pixels, and

the projection extends between the relay electrode and the signal line which are connected to each other via the semiconductor layer.

2. The display device of claim 1 , wherein

the scanning line has the projection in one of the sub-pixel which displays the most luminous color.

3. The display device of claim 1 , wherein in an extension direction of the signal line, a length of the projection is less than a length of the relay electrode.

4. The display device of claim 1 , wherein in an extension direction of the scanning line, the projection is located between the first position and the second position.

5. The display device of claim 1 , wherein

the relay electrode is in contact with the pixel electrode in a third position, and

in an extension direction of the signal line, a distal end of the projection is located between the first position and the third position.

6. The display device of claim 1 , wherein

in an extension direction of the scanning line, a first width of the sub-pixel without the projection is less than a second width of the sub-pixel with the projection.

7. The display device of claim 6 , further comprising a light-shielding layer opposed to the scanning line and the signal line, wherein

the light-shielding layer includes apertures respectively in the sub-pixels,

the aperture of the sub-pixel with the projection and the aperture of the sub-pixel without the projection have the same size as each other.

8. A display device comprising:

scanning lines;

signal lines crossing the scanning lines;

sub-pixels defined by the scanning lines and the signal lines;

a switching element in each of the sub-pixels;

a pixel electrode in each of the sub-pixels, wherein

the switching element includes:

a relay electrode in contact with the pixel electrode; and

a semiconductor layer in contact with the signal line in a first position, in contact with the relay electrode in a second position, and bending between the first position and the second position and crossing the scanning line, and

in at least one of the sub-pixels, a part of the scanning line extends between the relay electrode and the signal line which are connected to each other via the semiconductor layer, wherein

the scanning line includes a bent portion in at least one of the sub-pixels, and

the bent portion extends between the relay electrode and the signal line which are connected to each other via the semiconductor layer.

9. The display device of claim 8 , wherein the bent portion crosses the signal line.

10. The display device of claim 8 , wherein the bent portion obliquely crosses the signal line.

11. The display device of claim 8 , wherein the scanning line includes a first portion extending along a first line, a second portion extending along a second line, and the bent portion between the first portion and the second portion.
