In order to provide a display apparatus with high image quality which can detect a change in light on an entire display frame without any influence on user's appreciation, a rear-projection type display apparatus which projects irradiating light from a light source unit onto a fresnel screen through a light valve includes a light measurement unit which is placed at a position where reflected light from the fresnel screen is condensed, and a control unit which controls the light valve on the basis of the measurement result obtained by the light measurement unit.
