    摘要: An illumination unit includes an LED (2) and a tabular light guide plate (1) having a light emitting surface (110) for emitting light from the LED (2) as planar light, wherein a recessed portion (101) is formed in the opposite surface of the light emitting surface (110) of the light guide plate (1), and wherein the LED (2) is provided in the recessed portion (101) so that the optical axis of the LED (2) becomes parallel to the light emitting surface (110) of the light guide plate (1). Further, a plurality of LEDs (2) are arranged along the longer direction of the recessed portion (101), a dimming pattern (3) is provided at a location corresponding to each of a plurality of LED (2) of the light emitting surface (110) of the light guide plate (1), and the shape or the size of the dimming pattern is varied with a location on the light emitting surface (110) of the light guide plate (1).
