Abstract
The present invention provides a liquid crystal display and its manufacturing method for solving the problem that, in the conventional manufacturing method which curtails the number of production steps, if channel length is shortened, the production margin becomes small and the production yield is lowered. The four-mask process plan or the third-mask process plan of an TN (twist nematic) type liquid crystal display unit and an IPS type liquid crystal display unit is constructed by combination of techniques which consist of a technique of rationalizing a step of forming a scan line, and a step of forming an etch stop layer by introducing a half tone exposure technique; a technique of rationalizing a step of forming a protection layer of an electrode terminal, by introducing the half tone exposure technique into a step of oxidizing an anode of a source/drain wiring which is a known technology; and a rationalizing technique of forming simultaneously a picture element which is a known technology and the scan line.
