    Abstract: The present invention relates to heat-resistant and plarizers that use thin films of dichroic organic substances, mainly dichroic dyes applied on the surface of rigid or flexible substrates in which the molecules of the dichroic organic substance are arranged in the form of a crystalline grid. The purpose of this invention is to widen the spectral range of the polarizer operation while improving polarization characteristics. This dichroic polarizer includes a film having a portion at least consisting of a crystalline structure that comprises at least one dichroic organic substance, wherein the molecules or molecule fragments of this substance have a planar morphology. The dichroic substance consists of a dichroic substance having at least one crest on the spectral absorption curve within spectral ranges of 400 to 700 nm and/or 200 to 400 nm and 0.7 to 13 &mgr;m. The order parameter of the film S is defined by the formula S=(D⊥−D∥)/(D⊥+2D∥) in which D⊥ and D∥ represent the optical density measured in the polarized light during the perpendicular and parallel orientations, respectively, of the polarizer polarization axis relative to the polarization plane of an electromagnetic radiation from a spectrometer. This parameter corresponds to at least one crest on the spectral absorption curve within a spectral range of 0.7 to 13 &mgr;m, and has a value not less than 0.8.

    Abstract: The invention pertains to thermo-resistant and light-resistant dichroic polarizers based on thin films of dichroic matters, in particular organic dyestuffs, in which molecules are ordered in a crystalline structure and applied on the surface of the substrate. The dichroic polarizer is characterized by the fact that it contains at least one anisotropically absorbing film comprised of oriented molecules. Anisotropically absorbing film is characterized by the fact that for the major axes of the ellipsoids of the real and imaginary parts of anisotropic refraction coefficient in the range of at least one absorption band of the following is true on the area with linear dimensions no less than the maximum wavelength: K1≧K2>K3 ( n 1 + n 2 ) 2 > n 3 where K1, K2, K3 and n1, n2, n3, are main values of the semiaxes of the ellipsoid representing the imaginary and real parts, accordingly, of the anisotropic refraction coefficient, and/or the anisotropically absorbing film is characterized by the fact that light transmission by two films with cross-oriented polarization axes does not increase at least in some range of wavelengths upon the deviation of its propagation from the normal to the polarizer plane.

    Abstract: A liquid crystal display has a first substrate plate and a second substrate plate, and a liquid crystal layer disposed between the plates. A polarizing coating, having molecules of one or more organic dyes capable of forming a lyotropic liquid crystalline phase, is formed overlying a selected surface of each plate. Orientation of the polarizing coating is obtained by applying a force to the dye molecules when in the liquid crystal phase and subsequently converting the liquid crystal phase to a solid film.
