A projector which is small in size and excellent in light utilization efficiency while keeping the advantage of a spatially-pixel-arrangement type is provided. The luminous flux emitted from a light source is separated by a color separation system into a plurality of kinds of colors of light different in exit direction. These separated colors of light are modulated by a light valve, to form first optical images. The light valve has a plurality of sub-pixels provided corresponding to the colors of light and micro-lenses to focus the colors of light corresponding to the sub-pixels. The sub-pixels are structured in a size nearly equal to a size of a color of light to be focused on the relevant sub-pixel by micro-lenses. Accordingly, the first optical image is in a form non-analogous with the actual projection image. The first optical images are converted into second optical images having a desired aspect ratio by an anamorphic projection system, and then projected.
