LIGHTING APPARATUS, AND DISPLAY DEVICE PROVIDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lighting apparatus and a display device which have an effective emitting surface with a shorter frame length and less of unevenness of luminance without losing a light flux utilization ratio.

SOLUTION: A light flux direction changing part having two reflecting surfaces 12 is provided with a light guide plate 2 so that one end of the two reflecting surfaces may contact with a light incident surface 11 of the light guide plate, and a direction of the light flux from a light source is changed by a total reflection and an inside of the light guide plate 2 can have a uniform light flux distribution even if a size of a frame is small. For the above, the reflecting surfaces 12 are provided within a range of 20.02° or less against a perpendicular line of the light emitting surface of the light source.
