| 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.
