Dual domainlike, vertically aligned nematic liquid crystal display driven by in-plane field

A homeotropic liquid crystal display utilizing a liquid crystal with positive dielectric anisotropy, 13.3" XGA TFT-LCD, has been fabricated. The rubbing-free device, appears black in the absence of electric field. When an electric field generated by interdigital electrodes is applied, a bend deformation of molecular director to the direction of the field occurs and thus the cell transmits light, showing brightness uniformity in all directions owing to the dual domainlike director configuration. With an addition of négative-biréfringent film, this device shows excellent viewing angle characteristics.
