Patent ID: 7315338

Claim:
A liquid crystal display comprising a first plate, a second plate, and at least one layer of liquid crystal placed between the first and second plates, wherein on each of the plates there is formed at least one electrode or a system of electrodes or an active matrix, and wherein the first plate comprises at least one layer of O-type polarizer having negative dielectrical anisotropy and negative dichroism and the second plate comprises at least one E-type polarizer having positive dielectrical anisotropy and positive dichroism, wherein E-type polarizer is formed by the dichroic polarizer, which is realized as a film of oriented molecules of an organic matter wherein for the main axes of the ellipsoids of the real and imaginary part of its anisotropic refraction coefficient in the range of at least one band of absorption wavelengths the following is true for an area with the linear dimensions no less than the wavelength: K 1 ≥ K 2 > K 3 ⁢ ⁢ ⁢ and ⁢ ⁢ ( n 1 + n 2 ) > n 3 2 where, K 1 , K 2 , K 3 and n 1 , n 2 , n 3 , are main values of the real and imaginary part, respectively, of the axes of the ellipsoid, and/or the film is characterized by the fact that for two films with crossed polarization axes the transmission of light does not increase for at least a certain range of wavelengths with its direction declined from the normal to the polarizer plane.
