Claim Text:
1. A display apparatus comprising: a light emitting unit configured to emit light; a displaying unit configured to display an image on a screen by allowing the light from the light emitting unit to be transmitted therethrough at a transmittance based on an image signal, wherein the displaying unit comprises: a first measuring unit provided on a light-emitting surface of the light emitting unit, that detects a detection brightness comprising the brightness of light received directly from the light-emitting surface and the brightness of the return light; a correcting unit configured to correct the detection brightness which is the brightness detected by the first measuring unit, based on the brightness of the image displayed in a predetermined area corresponding to a position where the first measuring unit is provided; and a control unit configured to control the light emission brightness of the light emitting unit so that the detection brightness after correction by the correcting unit coincides with a predetermined target value, wherein the correcting unit reduces, so that a change in the detection brightness due to return light which is returned to radiate from the light-emitting-unit-facing surface is corrected, the detection brightness by a greater reduction amount, in a case where the image displayed in the predetermined area is dark, than a case where the image displayed in the predetermined area is bright, which is brighter than the dark image displayed in the predetermined area.
