A projection-type display apparatus includes at least one light source for emitting three primary color lights, a display panel, a control circuit for controlling the display panel, an illumination light optical system for illuminating the display panel with the light emitted from the light source, and a projection lens for projecting the light modulated by the display panel. The illumination light quantity is modulated by a control signal generated according to a video signal in at least one of the illumination color lights among the three primary color lights and the upper limit of the dynamic range of the display panel is used without depending on the video signal.
