Abstract
A liquid-crystal display having two carrier plates, between which a liquid crystal material is enclosed in hermetically sealed relation, and which have respective electrode coatings on their inner surfaces, at least one carrier plate having a polarizer disposed on the outer surface thereof, comprising a chemically inert, transparent and optically inactive protective foil and a dichroitic layer disposed between the protective foil and the carrier plate, with the marginal edges of the polarizer being covered with coating means for sealing the dichroitic layer from atmospheric influences, particularly humidity, and method of making the same.
