Zusammenfassung:PROBLEM TO BE SOLVED: To provide a light guide unit comprised of a plurality of light guide bodies with uniformity of luminance improved. SOLUTION: A light guide plate 12 with a plurality of light guide bodies each equipped with a light-emitting face for surface-emitting the light from a light source is so arranged to make the light-emitting faces in the same plane. At positions corresponding to joints 7 among the plurality of light guide bodies adjacently arrayed, a light volume adjustment part 14a is provided for compensating light volumes degraded due to the joints 7 by course changes of light irradiated from the light-emitting faces of the light guide bodies.
