ABSTRACT:
In the present invention, a liquid crystal projector has a reflective type liquid crystal element having opposed substrates and a liquid crystal layer between the substrates and projects a light image generated by the reflective type liquid crystal element. A orienting means of liquid crystal molecules provided in the reflective type liquid crystal element is a polyimide film with a vertical orientating characteristic as an orientation means. By rubbing the orienting means, a angle of inclination (pre-tilt angle) is predetermined. By using the reflective type liquid crystal element, the liquid crystal projector has a excellent light stability and a excellent display quality.
