An illumination device is constructed such that light illuminated by a light emitting element and transmitted through one side surface of a light guiding plate via an intermediate light guide is introduced into the light guiding plate and the light propagating in the light guiding plate is emitted from an output surface of the light guiding plate so as to illuminate a liquid crystal display unit (an illumination object) disposed behind the light guiding plate, such that a part of the light guiding plate, through which the liquid crystal display unit is displayed in a transmissive manner, serves as a display area, and such that the light guiding plate is formed so as to extend beyond the display area of the liquid crystal display unit and towards the light emitting element, along the longitudinal direction of the intermediate light guide. |
