Liquid crystal display device
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.
1. A display device comprising:
a plurality of pixel electrodes;
a plurality of video signal lines;
a plurality of scanning signal lines;
a counter electrode facing the plurality of pixel electrodes; and
a first metal wiring portion extending along one of the video signal lines and a second metal wiring portion extending along one of the scanning signal lines; wherein
the first metal wiring portion and the second metal wiring portion electrically connect to the common electrode.
2. The display device according to claim 1 , wherein a part of the metal wiring contacts the counter electrode and a part of the metal wiring does not contact the counter electrode in cross-sectional view along an extending direction of the scanning signal line.
3. The display device according to claim 1 further comprising:
an insulating film between the counter electrode and the plurality of video signal lines, wherein
the insulating film includes formation region on which a material of counter electrode is formed and non-formation region on which a material of counter electrode is not formed.
4. The display device according to claim 1 , wherein the video signal line extends while bends.
5. The display device according to claim 3 , wherein the non-formation region extends while bends along the video signal line.
6. The display device according to claim 1 , the metal wiring extends while bends along the video signal line.
7. The display device according to claim 3 ,
wherein the metal wiring overlaps the non-formation region at a position overlapping with the video signal line.
8. The display device according to claim 1 , wherein the metal wiring overlaps with the video signal line, and
a width of the metal wiring is thinner than a width of the video signal line.
9. The display device according to claim 3 ,
wherein the material of the counter electrode 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 ,
wherein an extending length of the non-formation is greater than a total length of two pixels.
12. The display device according to claim 1 , wherein the metal wiring having a first metal wiring portion and a second metal wiring portion, and
a width of the second metal wiring portion is wider than a width of the first metal wiring portion.
13. The display device according to claim 1 ,
wherein the first of the second metal wiring portion is vicinity a position where the video signal line crosses the scanning signal line in plain view.
