| description | PROBLEM TO BE SOLVED: To provide a planar lighting device that can restrain light leakage and attain suitable optical characteristics, and method for manufacturing the same.SOLUTION: The planar lighting device includes light source parts 1 to 5 having light emitting surfaces s1 for emitting planar light, and a frame 7 arranged at an outer peripheral side of the light source parts 1 to 5 and retaining the light source parts 1 to 5. The frame 7 is formed in a frame shape for surrounding the light source parts 1 to 5, and has a reflection part 7a for reflecting light, and an absorption part 7b integrally formed on at least a part of an outer peripheral side of the reflection part 7a and absorbing light. Connecting surfaces 7a1, 7b1 of the reflection part 7a and the absorption part 7b are inclined on an outer peripheral side against a direction perpendicular to the light emitting surface s1. |
