Abstract
In a liquid crystal display device the homogeneous alignment of twisted nematic liquid crystal molecules is accomplished by providing a first thin dielectric layer on the inner surfaces of each of the spaced apart glass plates covering complementary patterns of transparent electrode material. Applied to the dielectric layer on each plate is a second thin film of aligning material such as silicon monoxide. The first dielectric layer provides maximum isolation to the liquid crystal material and a uniform layer for subsequent application of the aligning film.
