<p>PURPOSE:To offer a color liquid crystal display element which is used suitably as a light valve for, specially, a single plate type liquid crystal projector. CONSTITUTION:The liquid crystal electrooptic element consists of a liquid crystal cell, formed by sandwiching nematic liquid crystal between two opposite arranged electrodes, and a couple of polarizing plates, and the twist angle of the liquid crystal is 80-100 deg.; and the couple of polarizing plates are so arranged that the axes of transmission or absorption cross each other at right angles and the axis of transmission or absorption of one polarizing plate deviates from the liquid crystal molecule orienting direction of an adjacent electrode substrate by 40-50 deg.. Then the retardation nd of a liquid crystal layer is at least >=0.9mum.</p> |
