The objective of the invention is to provide an highly efficient polarizer providing an improved brightness and color saturation of a LCI element based on such polarizer.This objective is to be attained by using, in manufacture of a polarizer and a 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 to create polarizers of both the dichroic and interference types. Further, the use of said layer allows to create 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 birefringent anisotropically absorbing layer having the abnormal dispersion allow to create both a color and monochromic LCI element distinguished for an higher brightness, color saturation, good angular characteristics and absence of shadows.
