Abstract
It is well known that slightly tilted homeotropic alignment of liquid-crystal molecules is obtained by oblique evaporation followed by homeotropic treatment. However, this method has disadvantages in obtaining large area uniformity and productivity because of the requirement of large vacuum equipment. In this paper, a new alignment technique of slightly tilted homeotropic alignment using the rubbing method (THR method) is proposed, and its applicability to display devices is discussed.
