Effect of Polarization Property on the Reflective STNLCDs Using Single Polarizer with Diffusing Reflector

Abstract

In order to prevent parallax, or decrease of resolution, in reflective LCDs, the diffusing reflector must be placed inside of the LC-cell, just behind of the liquid crystal layer, and near polarizer must be removed. In such single-polarizer-LCD, effect of the phase difference and depolarization of reflected light by diffusing reflector was evaluated. It is confirmed from the results that these problems were not severe for practical application of the LCDs.
