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.
