Patent ID: 7170481

Claim:
A liquid crystal display comprising: a substrate and a multi-layer stack of components of the display supported on said substrate, said display including only one said substrate, said components of the display comprising: a plurality of liquid crystal dispersion layers comprising: a first liquid crystal dispersion layer stacked over said substrate and a second liquid crystal dispersion layer stacked over said first liquid crystal dispersion layer; wherein said first dispersion layer and said second dispersion layer comprise regions of cholesteric liquid crystal material dispersed in a polymer matrix material; multiple electrically conductive layers including: a first electrically conductive layer stacked between said first dispersion layer and said substrate, an intermediate said electrically conductive layer stacked between said first dispersion layer and said second dispersion layer, and a second electrically conductive layer stacked over said second dispersion layer; and a protective polymer film layer, wherein said substrate forms one outer surface of the display and said protective film layer forms another outer surface of the display; and drive electronics adapted to electrically address said liquid crystal material of said first dispersion layer and said second dispersion layer between adjacent said electrically conductive layers effective to produce images from the display.
