Abstract
A method is disclosed for making a liquid crystal light valve in which the electro-optically active element is a liquid crystal composite sandwiched between two electrodes. The liquid crystal composite comprises plural volumes of liquid crystal material dispersed in a polymer matrix. By use of a tie layer, the problem of stress clearing is markedly reduced or eliminated. The tie layer material can be either a liquid crystal material or a telomer, crosslinkable or otherwise.
