Abstract
Light leakage within pixel area is prevented. A liquid crystal display device includes a light reflection area forming pixel electrode and a reflection film in one portion of a pixel area on a liquid crystal side face of one substrate oppositely arranged through the liquid crystal. A light transmission area forms the pixel electrode in another portion. The pixel electrode as the reflection film is formed on the upper face except for an opening portion of an insulating film. The opening portion is formed in a light transmission area. The opening portion of the insulating film has a fan-shaped taper from the substrate side to the liquid crystal side on the side wall face of this opening portion. At least one portion of this taper is not covered with the pixel electrode used as the reflection film, but is exposed. The insulating film has a light absorption property in at least the taper portion.
