Paper Abstract

A new type of a reflective liquid crystal display is proposed in a twisted hybrid aligned (THA) geometry. In this reflective configuration, a single polarizer and a reflective electrode are used to improve brightness and viewing characteristics. The electro-optical switching between the black and white states is easily achieved in the THA geometry. Numerical simulations are carried out to find the optimum cell parameters such as the cell thickness and the amount of twist required for a stable THA structure. The reflective THA cell provides wider viewing and faster dynamic characteristics than a reflective twisted nematic cell. The effect of a retardation film on device performances is also discussed.
