Abstract
An image display apparatus includes: a light source emitting light; a spatial light modulator having a display region, and modulating the light emitted from the light source in accordance with an image signal; a projection device projecting the light modulated by the spatial light modulator onto a projection surface including an illumination region; and a deflecting section deflecting the light that is emitted from the light source and is then incident on the spatial light modulator. In this structure, the light emitted from the light source illuminates a part of the display region of the spatial light modulator, the light is deflected by the deflecting section, and the illumination region illuminated by the light moves on the projection surface.
