ABSTRACT:
An optical compensation arrangement using tilted-optical-axis compensation films with negative birefringence for low-twist-angle nematic liquid crystal cells to achieve better viewing angle characteristics than a regular 90.degree.-twist TN cell, with similar high contrast ratio and brightness as the regular TN cell near normal incidence at a comparable operating voltage.
