Liquid crystal display device
View Patent ↗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 light shielding film;
an insulating film;
a plurality of video signal lines extending between the plurality of pixel electrodes;
a plurality of scanning signal lines extending between the plurality of pixel electrodes;
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 extending along one of the video signal lines or one of the scanning signal lines;
wherein a surface of the insulating film includes a formation region of the conductive film and a non-formation region of the conductive film, and
the metal wiring overlaps the non-formation region between the plurality of pixel electrodes, and contacting the counter electrode between the plurality of pixel electrodes.
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 scanning signal line.
3. The display device according to claim 1 , wherein the metal wiring extends along the video signal line.
4. The display device according to claim 1 , wherein the video signal line extends while bends.
5. The display device according to claim 4 , 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 1 , wherein the metal wiring covers 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 1 , wherein 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 further comprising:
a plurality of pixels each having the plurality of pixel electrodes,
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 portion and a second portion, and
a width of the second portion is wider than a width of the first portion.
13. The display device according to claim 1 , wherein the second portion is vicinity a position where the video signal line crosses the scanning signal line in plain view.
