Abstract
A lighting device includes a light source, a light reflecting unit, and a light diffusing unit. The light reflecting unit is arranged on an exit side of a light exit path with respect to the light source to reflect at least a part of a light emitted from the light source and transmit a part of the light. The light reflecting unit has an angle selecting property such that a reflectance of a light having a small incident angle becomes higher than a reflectance of a light having a large incident angle. The light diffusing unit is arranged between the light source and the light reflecting unit in the light exit path to diffuse the light.
