摘要： An illumination unit of the present invention includes a tabular light guide plate having a light emitting surface for emitting light coming from an LED as planar light, wherein a recessed portion is formed in the opposite surface of the light emitting surface of the light guide plate, and wherein the LED is provided in the recessed portion so that the optical axis of the LED becomes parallel to the light emitting surface of the light guide plate. Then, a dimming pattern is provided at a location corresponding to the LED of the light emitting surface of the light guide plate, and the dimming pattern includes a main portion covering the LED on the light emitting surface side, and protrusions radially extending toward a light emitting direction of the LED around the LED.
