Abstract
The lighting apparatus includes a light source, a housing that contains the light source inside and has an exit port for outputting light from the light source, and an optical sheet that is placed in the exit port. The optical sheet includes a lens structure that is placed at a light exit side and aligns an output direction of incident light from the light source, a reflector that is placed at a light incident side and reflects light emitted by the light source, and a light transmitting opening that exists in the reflector and transmits incident light from the light source. The light transmitting opening is placed in a position deviated from an optical axis of the lens structure. The display apparatus includes the lighting apparatus.
