Reflective supertwist nematic liquid crystal display with anterior retardation film

Color shift, viewing angle character and response speed for the in-plane switching super-twisted nematic cell are analyzed. The viewing angle depends on the change of the effective birefringence dΔn, the response time depends on the structure of liquid crystal display. The very wide viewing angle, fast resopnse times and low color shift are shown at any gray scales in this new mode. Potential applications for large screen refelctive displays are foreseeable.
