We have developed a novel vertical-alignment (VA)-π cell mode that provides a wide viewing angle and fast response times for a negative dielectric anisotropy nematic liquid crystal on homeotropic polyimide surfaces. Good voltage-transmittance curves and low driving voltages were achieved with the novel VA-π cell mode without negative compensation film. Iso-viewing angle characteristics were also successfully observed. A fast response time of 31.7 ms for the novel VA-π cell mode was also measured.
