Abstract
A liquid crystal type display system containing a liquid crystal layer with positive dielectric anisotropy located between two carrier plates whose mutually opposite surfaces each have an electrode coating as well as an insulation layer which has been vaporized on obliquely. A rotating display cell with obliquely vaporized-on layers is provided by choosing the vapor deposition angle for one of these layers in excess of about 75.degree. and for the other layer less than about 65.degree. and positioning the carrier plates in spaced relationship to one another without any substantial rotating of one plate relative to the other thereof.
