Abstract
An improved liquid-crystal display exhibiting both a relatively bright background and good contrast between the background and displayed characters is disclosed. The display includes a liquid-crystal contained between a pair of support plates carrying transparent electrodes. First and second polarizers of differing characteristics are positioned on opposite sides of the liquid-crystal and a suitable reflector is combined with one of the polarizers.
