Abstract

The electro-optical (EO) performances of a multidomain vertical-alignment (MVA) cell on a homeotropic photopolymer have been investigated. In the absence of an electric field, the MVA cell achieved black state as LC alignment is homeotropic. An electric field created by interdigitated electrodes and rib made after photolithograph using the photopolymer on both substrates causes a director deformation of a multidomain type. Good voltage-transmittance curves for a MVA cell on the homeotropic photopolymer were observed. Also, the stable response time of MVA cell on the homeotropic photopolymer can be achieved.
