<title>Overview on reflective liquid crystal displays using one polarizer</title>

Abstract

The electro-optic effect and viewing angle characteristics of some recently developed single-polarizer reflective liquid crystal displays are compared under same material parameters. The mixed-mode twisted nematic cells and biaxial film-compensated thin homogeneous cells are promising for both direct-view and projection displays employing crossed polarizers. How to improve contrast ratio for the parallel- polarizer displays remain a technical challenge.
