PURPOSE: To provide a high polymer dispersed liquid crystal display element with which a low driving voltage and high contrast are embodied. CONSTITUTION: The cholesteric liquid crystal compd. precursor expressed by formula is applied between two sheets of glass substrates 1 and 1 formed with ITO transparent electrodes 2 at 50 to 1000Åthickness and thereafter, nematic liquid crystals and the precursor of a high-polymer gel are injected therebetween and are irradiated with UV rays to effect photopolymerization, by which the hydrophilic sections 3 of the high-polymer main chains of the cholesteric liquid crystals 4 polymerized to a high polymer are made to exist only on the surfaces of the ITO transparent electrodes 2 and hydrophobic sections 5 are bordered with the nematic liquid crystal molecules 6 and the high-polymer gel 7. In the formula, (n) denotes an integer from 1 to 20; X denotes halogen, Y is >=1C hydrocarbon groups contg. at least one kind among hydrogen, oxygen, sulfur and nitrogen. |
