Semi-transmissive-type liquid crystal display device and method for manufacturing same

摘要

A semi-transmissive-type liquid crystal display device is provided which is capable of preventing an electric erosion reaction between a reflective film made of Al (aluminum) or an Al alloy and a transparent electrode film made of ITO or a like (Indium Tin Oxide) and of inhibiting occurrence of a flicker caused by a residual DC (Direct Current) voltage in the reflective film. In the semi-transmissive-type of a liquid crystal display device, a transmissive region to provide light from a backlight source and a reflective region to receive ambient light are placed in a pixel region and a transparent electrode film is formed above a reflective film formed in the reflective region on an active matrix substrate with a second passivation film being interposed between the reflective film and the transparent electrode film.
