ABSTRACT:
A heads-up display system includes a liquid crystal display unit that can change optical characteristics in accordance with a video signal. The light modulated by the liquid crystal display unit is projected on a surface of a transparent plate that can reflect the light so as to realize a projection display. The light projected on the transparent plate is polarized light having a transmission axis extending in a direction parallel to a line defining the center with respect to incident light and reflective light of the transparent plate.
