Abstract
A liquid crystal display device (60) having first and second polymeric substrates (30) and (62) and a layer of cholesteric liquid crystal material disposed therebetween. The cholesteric liquid crystal material is disposed in a plurality of channels (36), (38), and (40) formed in one surface (32) of one of said substrates. The liquid crystal material may be further adapted to reflect light of specific wavelengths, so as to affect a color liquid crystal display.

A liquid crystal display device comprising:
- a first substrate fabricated of an optically anisotropic polymeric material, said substrate having a layer of transparent conductive material disposed on at least part of one surface thereof;
- a second substrate fabricated of an optically anisotropic polymeric material, said second substrate having a plurality of channels formed on one surface thereof, said channels having a layer of transparent conductive material disposed therein, said second substrate being operatively positioned relative to said first substrate so that said channeled surface of said second substrate is in substantially parallel, facing relationship with said coated surface of said first substrate;
- and
- a layer of cholesteric liquid crystal material disposed in each of said channels.
