Liquid crystal display device.

摘要

Picture inversion in display devices, based on the twisted nematic effect is prevented by choosing a twist angle psi T in such a way that 40<o> < psi T < 90<o>, while it holds for the angle alpha between the direction of polarization of one of the polarizers and the associated direction of orientation that: 30<o> + psi T/2 < alpha < 60<o> + psi T/2. <IMAGE>
