Electro-optical display device with liquid crystals.

摘要

A first variant relates to a positive or negative anisotropy liquid-crystal electrooptical display cell comprising, between two crossed polarisers (P4 and P5), at least two monolayer identical elementary cells (A and B) stacked against one another so that their networks of electrodes coincide and they are each subjected simultaneously to the application of an electrical voltage. First application to a colour multiplexed display. Second application to a heat-stable multilayer cell. Third application to a multilayer cell with electronically adjustable circular or elliptical polarisers. <IMAGE>
