OPTICAL DEVICE FOR PRODUCTION AND/OR TRANSFORMATION OF POLARIZED ELECTROMAGNETIC RADIATION AND OPTICAL DEVICE IN THE FORM OF LIQUID CRYSTALLINE DISPLAY Russian patent published in 2003 - IPC

FIELD: production and/or transformation of polarized electromagnetic radiation. SUBSTANCE: the optical device has at least one molecularly oriented layer of low-molecular or oligomeric or dichroitic material capable of formation of stable liotropic liquid crystalline phase. The projection onto the surface of the molecularly oriented layer of the dipole moment of the optical transition of at least one anisotropic absorbing fragment of the molecule of dichroitic material is mainly parallel with the optical axis of the molecularly oriented layer, whose value of dichroitic ratio is not lower than 35 at least in a certain wave band of electromagnetic radiation. Such an optical device can be used in a liquid crystalline display as a polarizer or a phase retarding layer. EFFECT: enhanced efficiency of production and/or transformation of polarized electromagnetic radiation at preservation of a high thermostability and light stability and low thickness, as well as adaptability of streamlined production. 25 cl, 1 tbl
