Abstract:
1. A multilayer plate comprising an optically transparent substrate, a protective layer, a conducting layer, and at least one anisotropic thin crystal film made of a substance containing aromatic rings and possessing a structure with an interplanar spacing of 3.4±0.2Å, along with one of optical axes, wherein the at least one crystal film is situated between the substrate and the conducting layer and is separated from the conducting layer by the protective layer, and the substrate is made of a polymer or glass material transparent in the visible range and cutting off the UV radiation component, so that transmitting of the multilayer plate for UV radiation does not exceed 1% at any wavelength below 380 nm wherein the thin crystal film is a polarizer of the E type that simultaneously performs the functions of a polarizer and a phase-shifting layer; and wherein at least a part of the protective layer is conducting.
