EVALUATION OF THE TILTED HOMEOTROPIC ALIGNMENT OF LIQUID-CRYSTAL MOLECULES USING THE RUBBING METHOD

抄録

It is well known that small tilted homeotropic alignment of liquid-crystal molecules is obtained by oblique evaporation followed by homeotropic treatment. However, this method has disadvantage in obtaining large area uniformity and productivity because of requirement of a large vacuum equipment. To solve this problem, a new alignment technique of small tilted homeotropic alignment using rubbing method (THR method) is proposed. The THR method has advantage in obtaining large area uniformity and productivity because of non-requirement of a large vacuum equipment. In this paper, the applicability of this method for display device is discussed.
