Abstract
Computer simulations on the display characteristics of chiral-homeotro pic liquid crystal cells are performed. This normally black display mo de exhibits an excellent contrast ratio, nearly achromatic light trans mission, and low operation voltage. The optimal twist angle for suppre ssing the wavelength and voltage dependencies ranges from 90 degrees t o 150 degrees. Promising applications of this operation mode for both transmissive and reflective displays are discussed. (C) 1997 American Institute of Physics.
