Abstract

A light guide plate has a substantially flat shape and used as a backlight for an electronic appliance. The light guide plate introduces thereinto illuminating light emitted from a light source through part of a side surface thereof and directs the illuminating light out of the light guide plate through light emitting parts formed in a main surface of the light guide plate, in which a light-receiving surface for the illuminating light on the side surface is inclined relative to a plane perpendicular to the main surface. Thus, illuminating light is refracted, enters the light guide plate, and propagates in the light guide plate while undergoing total internal reflection. Light can be effectively directed out of the light guide plate through the light emitting parts. Thus, a light guide plate with which power saving and reduction in thickness can be achieved by improving light use efficiency, a wiring module in which the light guide plate is used, and an electronic appliance in which the light guide plate or the wiring module is used are provided.
