2a07 Liquid crystal molecular orientation properties in azimuthal rubbing cell

Abstract

TN liquid crystal cell, whose twisting angle is azimuthally distributed, is fabricated by combing azimuthal and normal rubbing substrates. The molecular orientation state with twisting angle up to ±90° is stable state, and it transits to that with the twisting angle up to 180° after applying sufficiently high voltage although the state is metastable. The ±180° twisting cell can apply to the polarization converting device to create radial polarization.
