Liquid crystal display
View Patent ↗A display portion is divided by scan lines and signal lines into sections where pixels are provided. Contact holes each for connecting common wiring and a common electrode together are not formed for all the pixels, but decimated so as to be arranged in zigzags.
1. An in-plane switching liquid crystal display, comprising:
thin film transistors on a substrate,
scan lines and signal lines connected to the thin film transistors and longitudinally and latitudinally crossing each other,
common wiring formed by the same layer as the scan lines and generating electric fields substantially parallel to the substrate between a common electrode connected to the common wiring and covering at least the signal lines partially via an interlayer insulating film formed on the thin film transistors,
a pixel electrode connected to the thin film transistors, and
contact holes connecting the common wiring and the common electrode to each other and are formed at a ratio of one contact hole to a plurality of the pixels with respect to the pixels divided and defined by the scan lines and the signal lines.
2. A liquid crystal display according to claim 1 , wherein:
when seeing, from one pixel formed with the contact hole, other pixels formed with the contact holes, respectively, and located around the one pixel, the other pixels are arranged at an interval of at least one pixel in longitudinal and latitudinal directions from the one pixel.
