| description | PROBLEM TO BE SOLVED: To provide a sidelight type planar lighting system improving the utilization efficiency of outgoing light from point-like light sources. SOLUTION: Fixed walls 16-19 extending from a housing frame 14 have first projecting parts 21-24 projecting alternately from the upper side and the lower side, at the tip parts. A light entry surface 11c of a light guide plate 11 has second projecting parts 25-28 respectively projecting to be vertically alternate with the first projecting parts 21-24, at the parts facing the respective fixed walls 16-19. The fixed walls 16-19 are connected to the light entry surface 11c by fitting the first projecting parts 21-24 and the second projecting parts 25-28. The respective point-like light sources are arranged in partitions 15a, 15b, 15c formed of spaces between the fixed walls 16-19. The camber and waviness of the light guide plate 11 are thereby straightened to improve the bonding efficiency of the point-like light sources and the light guide plate 11, and leakage light outgoing sideward and backward from the point-like light sources can be reflected and made incident to the light entry surface 11c.
