An image display apparatus includes a light source that emits light-source light, an illumination system that makes the light-source light uniform, a color separation system that separates illumination light outputted from the illumination system into color light fluxes, color optical modulators illuminated with the color light fluxes separated by the color separation system, and an optical element having an element surface the film thickness distribution of which is configured in such a way that the film thickness changes in a non-uniform manner.
