Microdeflection liquid crystal display modes using eight-division electrodes

Microdeflection liquid crystal display modes that use eight-division electrodes are investigated. According to the multidomain ge formation of the eight-division structure, a wider viewing angle and gentler decay of transmittance versus voltage characteristics are expected. Under He-Ne laser irradiation, the threshold voltage of the transmittance versus voltage characteristics depends on the polarization direction of the incident light in a manner similar to that of previously reported microdeflection liquid crystal display modes. This threshold voltage change is explained by molecular motion and domain formation. The contrast ratio obtained is 354 : 1. Under white light illumination and crossed polarizer configuration, the contrast ratio is 43 : 1.
