Title: Liquid crystal display element
Inventor: NAKAYAMA MASAHITO
IPC: G02F1/133
Filed: 1988-03-24
Abstract: PURPOSE:To substantially obviate the generation of domains, to easily obtain a uniform tilt angle and to substantially obviate the generation of unequal display by confining the difference in the tilt angles of orientation control films on both sides of a liquid crystal layer to 2-5 deg.. CONSTITUTION:This display has the liquid crystal layer which has 160-300 deg. twist angle by a nematic liquid crystal having positive dielectric anisotropy and a driving means for impressing voltages between transparent electrodes of upper and lower substrates sandwiching said liquid crystal layer. The difference of 2-5 deg. is given to the respective tilt angle of the orientation control films existing on both sides of the liquid crystal layer. The high tilt angle is thereby given to one orientation control film and, therefore, the domains are hardly generated even if the twist angle of the liquid crystal layer is 160-300 deg.. Since the tilt angle is low in the other orientation control film the uniform tilt angle is easily obtd. and the unequal display is hardly generated.
