摘要
Iso-contrast curves as a function of viewing angle between eight gray levels in sequence have been investigated for two-domain twisted nematic liquid crystal displays. The optimal twist angle has been found to be approximately 80-degrees. The two-domain 80-degrees-twisted nematic LCD shows a large viewing zone of +/-45-degrees in the vertical and +/-60-degrees in the horizontal directions without grayscale reversals. We have demonstrated a simple fabrication method which requires only one photo-lithographic exposure and a total of three independent rubbing directions on two polyimide-coated substrates.
