摘要

In this paper, it is reported that the electrooptic effect of an FLCD exhibiting half-V-shaped switching using an FLC material R2301 (Clariant Japan) that has no smectic A phase, depends on the surface alignment conditions such as photoalignment and rubbing. It is shown that an FLCD cell fabricated using the photoalignment technique, which produces a weak azimuthal anchoring, results in a superior EO performance in a low saturation operation voltage and in a wide cone (deflection) angle compared to those fabricated under a weak rubbing condition.
