PROBLEM TO BE SOLVED: To solve the problems of secular lowering of reflectance of a reflection structure near a light source and deterioration of assembly workability, and also, to achieve improvement of luminance uniformity.SOLUTION: A surface light emitting device at least has: a tabular light guide plate for emitting light entered from a side surface from a principal surface; a reflection sheet arranged at a back surface of the light guide plate; a substrate arranged facing the side surface of the light guide plate; a plurality of light emitting bodies aligned in a longitudinal direction of the substrate and mounted on the side of the substrate facing the light guide plate; and a frame for holding at least the substrate, the light guide plate and the reflection sheet from the principal surface side of the light guide plate, and a rear frame for holding them from the back surface side of the light guide plate. A reflection body is arranged in the vicinity of a part of the light emitting bodies along a side in the longitudinal direction of the substrate. |
