Abstract:
An illumination device includes a light guide member having a bar-like shape and a light source disposed so as to face an end surface of the light guide member. The illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member. The light emission surface includes a first light diffusing portion that is formed in a first portion near the light source and that has a protruding/recessed shape, and a second light diffusing portion that is formed in a second portion adjacent to an end of the first light diffusing portion, the end being away from the light source. The second light diffusing portion has a protruding/recessed shape and has lower light diffusivity than the first light diffusing portion.

Claim (Index 1):
An illumination device comprising:\n a light guide member that is made of a transparent material and that has a bar-like shape; and a light source that is disposed so as to face at least one end surface of the light guide member, wherein the illumination device guides light from the light source in the light guide member and emits the light from a light emission surface of the light guide member formed in a longitudinal direction of the light guide member, and wherein light emission surface includes, in the longitudinal direction;\n a first light diffusing portion, provided at a side of the light source, that diffuses the light, and \n a second light diffusing portion, provided between the first light diffusing portion and a central portion in the light guide member, that diffuses the the light, and \n the first light diffusing portion and the second light diffusing portion differ in shape.
