Abstract
A surface illuminant device includes a light transmitter, light sources disposed adjacent to entrance ends of the light transmitter, and a reflecting sheet disposed below a lower surface of the light transmitter. The entrance ends of the light transmitter are configured as rough surfaces, and thereby unevenness of brightness of the surface illuminant device can be lessened.
