Abstract
A holographically formed reflective display includes first and second substrates, a liquid crystal material located between the first and second substrates and a plurality of anisotropic polymer sheets separating the liquid crystal material into a plurality of liquid crystal material regions. The anisotropic polymer sheets reduce haze in the display and operates in the reverse mode when viewed from various viewing angles. The holographically formed reflective display may be used to form a color liquid crystal display and a color projection system.
