Abstract
A reflective liquid crystal display device having a structure providing high contrast even if there is undesired light. The structure includes a light-guiding plate for receiving, from a light-incident surface, light coming from a light source, and for allowing the light to exit from a bottom surface; a reflective liquid crystal display panel opposed to the bottom surface of the light-guiding plate; and a prism disposed on the side of a top surface of an upper substrate of the liquid crystal display panel. The prism has a surface that is substantially perpendicular to the top surface of the upper substrate, and a tilted surface which is tilted towards a side opposite to the light source from a crest line of the substantially perpendicular surface at a tilt angle with respect to an imaginary surface which passes through the crest line and which is parallel to the top surface of the upper substrate.
