ABSTRACT:
To respective pixel regions formed on a liquid-crystal side of one of a pair of substrates which are arranged to face each other in an opposed manner while sandwiching liquid crystal therebetween, pixel electrodes which reflect an external light incident on the pixel electrodes through the other substrate are provided. Protruding portions are formed on a surface of the pixel electrode in a scattered manner and the protruding portions have two or more kinds of shapes which are different from each other when the pixel electrodes are viewed in a plan view. The protruding portions formed on the surface of the pixel electrode are formed of island-like multi-layered material layers which are positioned at lower layer sides of the pixel electrodes. Due to such a constitution, the generation of the interference light can be suppressed.
