Abstract

A display device is provided and includes first and second substrates; a liquid crystal layer filled between the first and second substrates; a counter electrode pattern formed on the first substrate; scanning lines extending in a first direction; signal lines; and a first pixel electrode pattern and a second pixel electrode pattern formed on the first substrate, wherein the first pixel electrode pattern and the second pixel electrode pattern are located in line symmetry with respect to a first scanning line of the scanning lines.

Claims (67)

1. A display device comprising:

a substrate;

a first pixel with a first electrode on the substrate;

a second pixel with a second electrode on the substrate, the first pixel being adjacent to the second pixel;

a first scanning line between the first pixel and the second pixel;

a second scanning line, the first pixel being located between the first scanning line and the second scanning line; and

a third scanning line, the second pixel being located between the first scanning line and the third scanning line,

wherein

the first pixel electrode includes a first slit and a first contact hole,

the second pixel electrode includes a second slit and a second contact hole,

the first slit has:

a first end at a first scanning line side;

a second end at an opposite side of the first end; and

a first portion extending from the first end to the second end in a first direction, the second slit has:

a third end at the first scanning line side;

a fourth end at a an opposite side of the third end; and

a second portion extending from the third end to the fourth end in a second direction different from the first direction,

the first slit has:

the first end overlapping the first scanning line; and

the second end not overlapping the second scanning line, in a planar view, the second slit has:

the third end not overlapping the first scanning line; and

the fourth end overlapping the third scanning line, in the planar view,

the first contact hole is not located between the second end and the second scanning line, and

the second contact hole is not located between the third end and the first scanning line.

2. The display device according to claim 1 , wherein

the first pixel and the second pixel are arranged in a third direction,

the first direction is inclined at a first angle relative to the third direction,

the second direction is inclined at a second angle relative to the third direction, and

the second angle is an opposite direction of the first angle.

3. The display device according to claim 1 , wherein the first slit bends between the first end and the second end.

4. The display device according to claim 3 , wherein the second slit bends between the third end and the fourth end.

5. The display device according to claim 4 , wherein the first and second pixel electrodes have a vertical mirror structure with respect to the first scanning line.

6. The display device according to claim 1 , further comprising a counter electrode that is disposed in a same layer of the first pixel electrode.

7. The display device according to claim 1 , further comprising a counter electrode that is disposed in a different layer of the first pixel electrode.

8. The display device according to claim 1 , wherein

the first pixel electrode includes a plurality of the first slits,

the second pixel electrode includes a plurality of the second slits,

none of the first slits overlap any scanning lines at the second end in the planar view, and

all of the second slits overlap the third scanning line at the fourth end in the planar view.

9. A display device comprising:

a substrate;

a first pixel with a first electrode on the substrate;

a second pixel with a second electrode on the substrate, the first pixel being adjacent to the second pixel; and

a scanning line between the first pixel and the second pixel,

wherein

the first pixel electrode includes a plurality of first slits,

the second pixel electrode includes a plurality of second slits,

each of the first slits has:

a first end at a scanning line side;

a second end at an opposite side of the first end; and

a first portion extending from the first end to the second end in a first direction, each of the second slits has:

a third end at the scanning line side;

a fourth end at an opposite side of the third end; and

a second portion extending from the third end to the fourth end in a second direction different from the first direction,

all of the first slits overlap the scanning line at the first end in a planar view, and

none of the second slits overlap the scanning line at the third end in the planar view.

10. The display device according to claim 9 , wherein

the first pixel and the second pixel are arranged in a third direction,

the first direction is inclined at a first angle relative to the third direction,

the second direction is inclined at a second angle relative to the third direction, and

the second angle is an opposite direction of the first angle.

11. The display device according to claim 9 , wherein each of first slits bends between the first end and the second end.

12. The display device according to claim 11 , wherein each of second slits bends between the third end and the fourth end.

13. The display device according to claim 12 , wherein the first and second pixel electrodes have a vertical mirror structure with respect to the scanning line.
