Summary: 
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 negative-birefringent film, this device shows excellent viewing angle characteristics.
