ABSTRACT:
Devices of information displays, in particular liquid crystal displays, which can be utilized in indication devices for various purposes. Liquid crystal displays, according to this disclosure, contain at least one layer of liquid crystal placed between two plates, on each plate there has been formed or applied at least one electrode or a system of electrodes, or an active matrix, and at least one layer of polarizer; while at least one polarizing layer is an E-type polarizer and at least one polarizing layer is an O-type polarizer.
