摘要：
The invention relates to an active matrix liquid crystal display device which uses a switching device to control a pixel, and an object is to provide a liquid crystal display device which has an excellent viewing angle property and high brightness and a fabrication method of the same. A TFT substrate has a structure which reduces the film thickness of a protective insulating film in a control capacitance part in which control capacitance is formed and the film thickness of a protective insulating film in an auxiliary capacitance part in which auxiliary capacitance is formed thinner than the film thickness of a protective insulating film which covers a TFT and the other elements.
