Abstract

A projection apparatus including an illumination system, a light valve, an optical actuation element and a projection lens is provided. The illumination system provides an illumination beam. An image display surface of the light valve includes a first region and a second region. First pixels of the first region convert the illumination beam into first sub-image beams. Second pixels of the second region convert the illumination beam into second sub-image beams. A transmission path of one of the first sub-image beams in the optical actuation element is a first transmission path. A transmission path of one of the second sub-image beams in the optical actuation element is a second transmission path. A length of the first transmission path is smaller than a length of the second transmission path. In this way, the projection apparatus has good image quality.
