Abstract

A liquid crystal display device in which smear error is suppressed and transmittance is uniform is provided. In a liquid crystal display device which includes a plurality of pixels and uses comb-teeth-shaped transparent conductive films 110 as common wirings, the common wirings include mesh-shaped common metal wirings 101 v and 101 h extending in a vertical direction and a horizontal direction and the comb-teeth-shaped transparent conductive films 110 are connected between adjacent pixels.

Claims (22)

1. A display device comprising:

a plurality of pixels;

an insulating film;

a plurality of video signal lines;

a plurality of scanning signal lines;

a plurality of pixel electrodes in the plurality of the pixels;

a counter electrode formed commonly for the plurality of the pixels, formed of a conductive film, formed on the insulating film; and

a metal wiring contacting the counter electrode, and extending along one of the plurality of video signal lines or one of the plurality of scanning signal lines;

wherein a surface of the insulating film includes a formation region of a conductive film as the counter electrode and a non-formation region of the conductive film, and

the metal wiring covers the non-formation region at a position overlapping with one of the plurality of video signal lines or one of the plurality of scanning signal lines.

2. The display device according to claim 1 , wherein a part of the metal wiring contacts the conductive film and a part of the metal wiring doesn't contact the conductive film in cross-sectional view along an extending direction of the plurality of scanning signal lines.

3. The display device according to claim 1 , wherein the metal wiring extends along the plurality of video signal lines.

4. The display device according to claim 1 , wherein one of the plurality of video signal lines extends while bends.

5. The display device according to claim 4 , wherein the non-formation region extends while bends along the plurality of video signal lines.

6. The display device according to claim 1 , the metal wiring extends while bends along the plurality of video signal lines.

7. The display device according to claim 1 , wherein the metal wiring covers the non-formation region at a position overlapping with one of the plurality of video signal lines.

8. The display device according to claim 1 , wherein the metal wiring overlaps with one of the plurality of video signal lines, and

a width of the metal wiring is thinner than a width of at least one of the plurality of video signal lines.

9. The display device according to claim 1 , the conductive film is a transparent conductive film.

10. The display device according to claim 1 , wherein the counter electrode has a first part and a second part adjacent to the first part via the non-formation region, and

the first part and the second part are supplied same potential.

11. The display device according to claim 1 , an extending length of the non-formation is greater than a total length of two pixels.
