Reflective liquid crystal display device

摘要

A reflective liquid crystal display device having a structure which makes it possible to provide high contrast even if there is undesired light. The structure includes a light-guiding plate for receiving from a light-incident surface thereof light coming from a light source, and for allowing the light to exit from a bottom surface; a reflective liquid crystal display panel disposed so as to oppose 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 of the substantially perpendicular surface and which is parallel to the top surface of the upper substrate.
