摘要: According to one embodiment, a lighting device includes a radiation surface, at least one light source provided to face the radiation surface, and an optical control member provided between the radiation surface and the light source and includes optical characteristics of transmission, diffraction, diffusion, and reflection, which vary for regions in the optical control member, a distribution of each of the optical characteristics being determined by positions relative to the at least one light source. The optical control member is formed in a sheet shape which is controlled by at least one of a reflective film having a reflection factor distribution, and a reflective film having a numerical aperture distribution, and lenses.
