PSA Technology Development Applying Photo-polymerizable Monomer

Abstract

We review our developed PSA (Polymer Sustained Alignment) technology, which realize multi-domain VA (vertical alignment) of Liquid Crystal molecule by both applying fish-bone pixel electrode design and forming the polymer layer in the Liquid Crystal cell using photo-polymerization. PSA technology successfully improved image quality of VA-LCDs and is still widely applied for LCD panels by cost-effective simple processes today.
