: A prototype was developed of a novel display that includes a pi‐cell switching device with a special optical compensation system called a complementary pi‐cell structure(CPS) and a special drive method, called cyclic resetting(CR) drive. The pi‐cell is sandwiched between two optical films made of a negative Δn discotic liquid crystal (DLC), which is optically complementary to the pi‐cell. Thus, the CPS provides an extremely wide viewing angle. The CR drive method in which black voltage is applied to a pixel for a fraction of each frame, enables impulsive emission which improves the quality of motion picture display.
