Abstract
A lighting device includes a light source, a light diffusion plate, and a sheet-like optical member. The light diffusion plate is arranged opposite the light source. The light diffusion plate diffuses light from the light source. The optical member is disposed between the light diffusion plate and the light source. The optical member includes a transmitting part that transmits the light emitted from the light source and a reflecting part that reflects the light emitted from the light source. The optical member is supported by a support portion that is integrally provided to the light diffusion plate.
