Optical configurations of non-twisted liquid crystal cells for single-polarizer reflective displays

In this paper we introduce optical configurations of single-polarizer non-t wisted liquid crystal cells for high-contrast reflective displays that can be applied to vertical-switching modes as well as horizontal-switching mode s. In particular, optical configurations that can provide high contrast wit hout using a wide-band quarter-wave film are proposed. By fabricating refle ctive cells with the introduced configurations, we demonstrate their optica l performance. (C) 2001 Elsevier Science B.V. All rights reserved.
