Liquid crystal display device having particular twist angle, INCREMENT nd, INCREMENT epsilon , and threshold voltage

摘要

A TN-mode, normally-white format liquid crystal display device having high contrast and exceptional display characteristics. The angle of gradation inversion is increased and a straight-on contrast of more than 100 is obtained by setting the twist angle to 78 DEG -90 DEG , preferably 84 DEG -90 DEG , DELTA nd to 0.3-0.4 mu m, preferably 0.35-0.38 mu m, and DELTA epsilon to at least 6.2.
