A Wide-Viewing-Angle π Cell Compensated with a Discotic Film
Summary :
We have realized excellent viewing angle characteristics for the π cell, by combining a discotic negative birefringence film, which has a hybrid alignment structure, and a positive a-plate. The negative birefringence of the film completely compensates the positive birefringence of the π cell liquid crystals in the dark-state. The roll of a c-plate, which should be accompanied by the a-plate to suppress the light leakage from crossed polarizer at oblique incident angles, was substituted for the vertically aligned component of the π cell liquid crystal. Taking into account the fast electrooptical response, which is one order faster than that of the twisted-nematic liquid-crystal display, the π cell is one of the most promising liquid-crystal-display modes.
