Abstract

A lighting apparatus is held by a chassis and includes a plurality of LED modules emitting light toward an outer edge portion of the chassis and a light guiding plate for controlling the direction of light emission from the plurality of LED modules to perform illumination. The LED module is not arranged at the outer edge portion of the chassis so that moment acting on the chassis as the apparatus main body holding the LED module can be reduced as compared with the case where the LED module is arranged at the outer edge portion of the chassis. Therefore, the deformation such as bending of the chassis can be prevented.
