An image display apparatus includes a light source that generates light-source light of a plurality of colors, at least one optical modulator that corresponds to the light source and modulates image light of each of the light-source light of the plurality of colors, a display drive unit that controls the operation of the optical modulator according to an input image signal to perform display, a signal determining unit that determines whether the image signal has been input and whether the image signal can be processed by the display drive unit, and determines that a display state is non-normal when the image signal has not been input or when the image signal cannot be processed by the display drive unit, and a controller that, when the signal determining unit determines that the display state is non-normal, generates only at least one specific color light of the light-source light of the plurality of colors and simultaneously transmits a display image signal for non-normal display to the optical modulator.
