Abstract

This paper investigates the multi-dimensional liquid crystal (LC) alignment effect of a polymer wall. The polymer wall is formed on the pixel boundary by an anisotropic phase separation method, which affects the nearby LC orientation. Vertically aligned (VA) LC cells are fabricated in order to show the effect of the polymer wall on LC displays. The electro-optic characteristics of the LC cell are affected by the shape and orientation of the molecules that form the polymer wall. The VA LC cell that has a polymer wall formed by vertically-aligned anisotropic-molecules on the pixel boundary shows much faster turn-on and turn-off times than the conventional LC cell without polymer wall, as well as no loss of transmittance within its pixel area.
