Liquid crystal display apparatus having superimposed portion of common signal electrode, data signal wiring and scanning wiring via insulator

摘要

A liquid crystal display apparatus which has a large pixel aperture ratio, a high luminance and good yield without causing any signal delay on wiring or increasing any driving voltage. In a structure in which a capacity is formed on a superimposed part of a common signal electrode CE and at least one of a data signal wiring DL and a scanning signal wiring GL via an interlayer insulating film PAS, of insulating films included in the interlayer insulating film PAS, at least a layer OIL1 is selectively formed at least on a part of a region on a pixel electrode PX.
