Abstract: We demonstrate a new patterned vertical alignment liquid crystal display showing the reduction of the gamma distortions by forming the liquid crystalline polymer (LCP) layer, made of reactive measogens, on the homeotropic alignment surface. Here, the LCP layer was constructed through a spin-coating process of a reactive mesogen mixture, followed by the photo-polymerization and the wash process. It was found that the control of the exposure time during the photo-polymerization plays a key role in realizing the stable and uniform homeotropic alignment of the liquid crystal molecules on the LCP layer. This simple technique enables to produce multi-domains where the shift of the threshold voltage is spontaneously achieved domain by domain in the operation of the voltage division.
