Beschreibung
Zusammenfassung:	The present invention relates to an improved Liquid Crystal Display Device comprising, a pair of transparent substrates, each substrate having on one of its surfaces a coating of a transparent electrically conducting material which serves as an electrode. A nematic discotic material is sandwiched between the coated surfaces of the said substrates thereby forming a cell. The cell may be placed between a pair of cross polarizers.
