Fast Eight-Domain Patterned Vertical Alignment Mode with Reactive Mesogen for a Single-Transistor-Driving

Abstract

We proposed a wide-viewing patterned vertical alignment (PVA) mode with eight-domains driven by a single transistor. The eight-domain PVA mode was fabricated by introducing two different pretilt angles in a pixel using polymerized reactive mesogens (RMs) within alignment layer. The pretilt angles are simply controlled by an applied voltage during illumination of ultraviolet light for polymerization of the RMs. In addition, the polymerized RMs give rise to defect-free transition in our advanced PVA mode and thus fast response can be achieved over whole grey level.
