Abstract
Provided are a reflective liquid crystal display and a light guide plate capable of eliminating a decline in virtual contrast properties of a display screen in a reflective liquid crystal display comprising a light guide plate with a prism unit so as to display an excellent image. An antireflective film (40) is formed on a planar surface of a light guide plate (50) which is disposed so as to face a viewing side of a liquid crystal display panel (10). The antireflective film (40) inhibits light reflection on the planar surface of the light guide plate (50). Moreover, an adhesive layer (51) is provided to improve the adhesion of the antireflective film (40) to the planar surface of the light guide plate (50).
