Abstract

PURPOSE: To prevent liquid crystal from decomposition and deterioration by providing polyimido macro-molecule membrane in the position between a transparent conductive membrane and a liquid crystal layer as an ultraviolet rays absorption and reflection preventing layer.
CONSTITUTION: In respect to a guest host type liquid crystal display device which does not require a polaroid plate and has wide visual angle, transparent conductive membrances 5 and 6 are attached to glass base plates 3 and 4 respectively and polyimido macro-molecule membranes 12 and 13 are formed so as to cover both membranes 5 and 6 and base plates 3 and 4. Base plates 3 and 4 are connected through sealing agents 9 and 10 and guest host type liquid crystal mixture 11 is poured into the cell to make a liquid crystal display element. Since polyimido membranes 12 and 13 well absorb ultraviolet rays and, at the same time, act as reflection preventing layers, the decomposition and deterioration of liquid crystal mixture 11 caused by ultraviolet rays and the generation of decomposed gas can be prevented, obtaining a long life display device which can be easily observed without addition of an ultraviolet filter layer.
