ABSTRACT:
In a liquid crystal display device disposed with reflective regions and transmissive regions, two organic insulating films are formed on a connection terminal portion and radial non-uniformities are prevented from occurring when applying the upper organic insulating film. Pixel portions including transmissive regions and reflective regions are formed, and a second organic insulating film is formed between a metal layer that forms reflective electrodes and a transparent conductive film that forms pixel electrodes to planarize concavo-convexities in the reflective electrodes. In contact holes of a connection terminal portion, the inclination of a first organic resin film is made smooth to control the occurrence of radial non-uniformities occurring in the second organic insulating film.
