Liquid crystal display.

摘要

A ferro-electric liquid crystal display is adapted for viewing by reflection of light from the display. Each cell (12) of the display has a transparent front electrode (14) and a reflective back electrode (13). A polariser (17) is mounted in front of the display which is an odd number of quarter wavelengths in thickness. The polariser is orientated relative to the display to provide a maximum contrast ratio between the two cell conditions.
