The invention relates to light polarizers and devices for displaying information based on said polarizers, in particular to a liquid crystal indicating (LCI) element, and can be used on flat liquid-crystal displays, including those of the projection type, luminairs, optical modulators, matrix systems of light modulation, etc. The objective of the invention is to provide a highly efficient polarizer providing an improved brightness and color saturation of an LCI element based on such polarizer. This objective is to be attained by using, in manufacture of a polarizer and an LCI element based on such polarizer, at least one birefringent anisotropically absorbing layer having at least one refraction index that grows as the polarized light wavelength increases., i.e., having the abnormal dispersion. The use of said layer allows creation of polarizers of both the dichroic and interference types. Further, the use of said layer allows creation of a polarizer that provides, in a relatively simple design, conversion of practically all energy of a non-polarized radiation into the polarized radiation. The above-recited peculiarities of the claimed polarizer based on a birefrigent anisotropically absorbing layer having the abnormal dispersion allow creation of both a color and monochromatic LCI element distinguished for a higher brightness, color saturation, good angular characteristics and absence of shadows.
