We investigated the wide viewing angle and the fast response time characteristics for negative dielectric anisotropy nematic liquid crystal (NLC) using a vertical-alignment (VA) mode on a rubbed polyimide (PI) surface. Good voltage-transmittance (V-T) curves using a VA - 1/4 π cell and a VA-π cell without a negative compensation film were measured. The iso-viewing angle characteristics using a VA - 1/4 π cell and a VA-π cell without a negative compensation film can be achieved. The fast response time of 24.2 ms for NLC was successfully observed. Consequently, the iso-viewing angle, fast response time, and low driving voltage characteristics using a VA -1/4 π cell and a VA-π cell on a rubbed PI surface can be achieved.
