ILLUMINATION UNIT AND DISPLAY APPARATUS USING THE SAME
First Claim
1. An illumination unit, comprising a light emitting element as a light source and a tabular light guide plate having a light emitting surface for emitting light from the light source as planar light, wherein a recessed portion is formed in an opposite surface of the light emitting surface of the light guide plate, and the light emitting element is provided in the recessed portion so that an optical axis of the light emitting element becomes parallel to the light emitting surface of the light guide plate;
- wherein a dimming pattern is provided on the fight emitting surface of the light guide plate at a portion positionally corresponding to the tight emitting element;
wherein a first light guide pattern is provided on the light emitting surface of the light guide plate; and
wherein a second light guide pattern is provided on a rear surface of the light guide plate
