Disclosed herein is a display apparatus, including a plurality of pixel circuits disposed in a matrix at positions at which a plurality of signal lines and a plurality of scanning lines cross each other and individually including a light emitting element, a light emission driving section adapted to apply a signal value to each of the pixel circuits to cause the pixel circuit to emit light of a luminance corresponding to the signal value, and a light detection section including a light detection element which functions as a switching element by switching the light detection element between an on state and an off state and functions as a light sensor for detecting light from the light emitting element in the off state, the light detection section further including a detection signal outputting circuit formed in the light detection section for outputting light detection information from the light detection element.
