Abstract

We investigated the improvement using a new patterned double twisted(PDT) vertical-alignment(VA) cell mode on a homeotropic alignment layer. Good voltage-transmittance curves for negative dielectric anisotropic nematic liquid crystal (NLC) using a new PDT-VA cell without a negative compensation film were obtained. The viewing angle of a new PDT-VA cell without a negative compensation film was sider than that of a conventional VA cell. Finally a few fabrication processes using a new PDT-VA cell mode can be achieved by only one-side rubbed substrate.
