arranged in parallel, a plurality of light-guiding members arranged along a direction
wherein the LED light sources are arranged, a light reflecting part arranged on
one side face of the light-guiding members, a light diffusion part arranged on
an other side face of the light-guiding members, a light semi-transmitting reflection
part arranged between the LED light source and the light diffusion part, and an
optical path changing part arranged above the light-guiding members. A side of
the light-guiding members that faces the light diffusion part is flat.
