Abstract
An illuminating unit of the disclosure includes a light source, a plurality of optical members for illumination that guide light from the light source to a predetermined optical path, and a polarization split element that transfers, to a predetermined illuminating position, a first polarized component included in the light guided to the predetermined optical path. One or more of the plurality of optical members for illumination have optical properties, for the light at a predetermined wavelength band outputted from the light source, of guiding the first polarized component to the predetermined optical path, and guiding a second polarized component that is different from the first polarized component toward a direction deviated from the predetermined optical path.
