Liquid crystal image projection system.

摘要

A liquid crystal image projection system projects an enlargement of an image formed in an active matrix liquid crystal panel (17) onto a screen (19) by using a lamp (15) and a projector lens (18). The orientation of the liquid crystal panel is made such that a molecular axis vector (37) directing from an input light side end to an output light side end of each liquid crystal molecule in the middle of the liquid crystal layer has a vector component opposite to a scanning direction of the panel, and a convergent light is entered into the liquid crystal panel. The system can solve the problem of nonuniformity of the signal voltage-transmittance characteristic of the entire screen.
