Abstract
The key point to widen the veiwing angle of a TN-LCD is to realize a birefringent film with its optical axis tiled with respect to the display plane. We performed a negative tilted uniaxial film with holographically recorded volume index gratings in the form birefringence regime and studied the characteristics of such compensator in terms of viewing angle of a TN-LCD.
