Abstract
A liquid-crystal display using the twisted nematic mode was developed for an automotive instrument panel. A low viscosity, quick response liquid crystal of wide nematic range was designed with the aid of the molecular theory for viscosity of liquid crystals. A liquid crystal less than 20 cp at 25 degree C with wide mesomorphic range was developed. For the most uniform response and widest viewing angle, a liquid crystal molecular alignment of low tilt angle was developed. A simple rubbing alignment technique was used which is compatible to glass sealing.
