Wide Viewing Angle of Nematic Liquid Crystal Using the Vertical-Alignment-1/6π Cell on a Rubbed Polyimide Surfaces

Jeoung-Yeon Hwang, Dae‐Shik Seo, Jae-Hyung Kim

Abstract

The wide viewing angle characteristics of negative dielectric anisotropy nematic liquid crystal (NLC) using the vertical-alignment (VA)-1/6π cell on a homeotropic rubbed polyimide (PI) surface were investigated. Good voltage-transmittance characteristics using the VA-1/6π cell without a negative compensation films were obtained. The iso-viewing angle characteristics using the VA-1/6π cell without a negative compensation film can be achieved.
