Abstract
A liquid crystal display device comprising a pair of transparent substrates each provided with a transparent conductive film on the interior surface, boron nitride coating layers disposed on inner surfaces of the substrates and the conductive films, and a liquid crystal material interposed between the coating layers, the boron nitride layer being given preferred directions for aligning the molecules of the liquid crystal material. This structure increases the chemical stability and improves the alignment of the molecules of the liquid crystal material to a great extent.
