An illuminating apparatus comprises a light source and an optical system for guiding the light from the light source to an imager such as a liquid crystal panel. The optical system has an optical element disposed for changing a traveling direction of the light traveling to the imager in accordance with a control signal. The optical element is controlled such that, out of all pixel regions on the imager, part of the light amount to be applied to low-brightness pixel regions is distributed to high-brightness pixel regions.

An optical element includes a mirror surface configured to transmit certain part of incident light and to reflect the other part of the incident light. The mirror surface has a first region and a second region. The first region includes a first polarization conversion layer configured to convert a polarization direction of incident light incident on the first region from one linear polarization into a different linear polarization. A region of the optical element from which light transmitted through the first region is emitted includes a second polarization conversion layer configured to convert a polarization direction of the light transmitted through the first region from the different linear polarization into the one linear polarization.
