PROBLEM TO BE SOLVED: To provide a display device which can prevent the degradation in luminance on a light exit side for a long period and can efficiently emit light. SOLUTION: This display device has a light emitting element 1 and a light transmission body 2 having a light incident surface 35 and a light exit surface 36. The light transmission body 2 is fixed by a cover 8. The incident light on the light incident surface 35 of the light transmission body 2 is reflected by the cover 8 and is emitted from the light exit surface 36 approximately forming 90 deg. with the light incident surface 35. |
