摘要： A light guiding plate is provided on the obverse side of a display for displaying a display image while varying the display image. Unevenness is formed at a predetermined position at a reverse surface of the light guiding plate. A light emitting element is disposed at the side surface of the light guiding plate in such a manner as to introduce the light to the light guiding plate. Alternatively, an uneven portion in conformity with a pattern of a desired display image may be formed at a reverse surface of the light guiding plate, and a light emitting element is disposed at the side surface of the light guiding plate in such a manner as to introduce the light to the light guiding plate.

摘要： A lighting unit for illuminating a liquid crystal panel includes a point light source and a light guide. The light guide includes a first side surface extending in a direction x and having a light incidence portion facing the light source, a second side surface extending in a direction y perpendicular to the direction x, a third side surface spaced from the second side surface in the direction x, and an outlet surface for exit of light. The second side face is formed with a plurality of recesses each including a slant surface for causing light emitted from the light source to be reflected toward the third side surface. The recesses progressively increase in depth as they are positioned farther from the light source.
