Abstract:
1. A projector comprising: an illumination optical system; an incident-side polarizing plate which is disposed at a position at which light emitted from the illumination optical system is incident; a wire grid element which is disposed at a position at which the light passing through the incident-side polarizing plate is incident; a liquid crystal panel which is disposed at a position at which the light passing through the wire grid element is incident; and an exit-side polarizing plate which is disposed at a position at which light reflected by the wire grid element in the light modulated by the liquid crystal panel and incident on the wire grid element is incident, wherein a reference surface is perpendicular to the thickness direction of a liquid crystal layer of the liquid crystal panel, a reference direction is parallel to the reference surface, a rotational angle φ a rotational angle φ a rotational angle φ a rotational angle φ a lightness Tw is a lightness of the liquid crystal panel at a lightest display, a lightness T all Equations (1) to (3) below are satisfied: where f
