The projection display includes a light projector unit for generating and projecting light, an oscillator unit for oscillating light projected from the light projector unit, and a frequency generation and modulation unit. The frequency generation and modulation unit drives the oscillator unit and modulates the light projected by the light projector unit. In turn, the oscillator unit oscillates the light projected by the light projector unit in two dimensions, so that the projected light scans an incident surface in a raster pattern. At the same time, the frequency generation and modulation unit modulates the light produced by the light projector unit in synchronization with the scanning process and image data supplied so that the projected light produces images corresponding to the image data over a scanned area.
