Abstract
The wide viewing angle and fast response time characteristics of negative dielectric anisotropy nematic liquid crystal (NLC) using a novel vertical-alignment (VA)-1/4π cell mode on a homeotropic alignment layer were investigated. Good voltage-transmittance curves and low driving voltage using the novel VA-1/4π cell mode without a negative compensation film were obtained. The iso-viewing angle characteristics of NLC using the novel VA-1/4π cell mode without a negative compensation film can be achieved. The fast response time of 24.4 ms in NLC was successfully measured. The iso-viewing angle, fast response time, and low driving voltage characteristics using the novel VA-1/4π cell mode can be achieved.
