Abstract
A liquid crystal display includes plural liquid crystal picture elements selectively operable to affect light by scattering or absorbing light or by reducing such scattering or absorption of light, a separator integral with and between respective picture elements, the separator being substantially non-selectively operable to affect light and including spacers between respective picture elements forming a grid of spacers and picture elements and overlying parts of respective driving TFT transistors or the like so they do not detrimentally affect an image or in effect mask out drive elements from being seen in the displayed image or projected image. The liquid crystal may have a birefringence in the range of about 0.12 or less and may be used in a projection system in which an image is formed from nonspecular light.
