2a08 Optical properties of patterned cells with homogeneous and twisted nematic orientation domains

Abstract

We investigated transmitted light intensity-applied voltage characteristics of patterned liquid crystal (LC) cells with microscale homogeneous and twisted nematic (TN) orientation domains. It was revealed that the transmitted light intensity-applied voltage curve is sensitive to the domain size; that is, the driving voltage is reduced as the domain size decreases. This phenomenon is likely to be caused by the increased tilt angle which is induced by the microscale rubbing pattern.
