Abstract:
Disclosed are a luminous flux control member, which includes an incident surface onto which a light is incident, a reflective surface reflecting the incident light, and a light exit surface outputting the reflected light according to at least two orientation angles based on one direction perpendicular to a central axis connecting a center of the incident surface with a center of the reflective surface, a light emitting device and a display device having the same. The uniformity in the brightness of the display device is ensured and the display device is realized in small size.
