  • Electroluminescene device with emission of polarized light
    Patent number: 6040069
    Abstract: The invention relates to an electroluminescence device having at least one light-emitting layer which comprises conjugated, stiff-chain polymers which are soluble in organic solvents, wherein the emitted electroluminescence is polarized and the intensity of the light which is polarized parallel to the longitudinal axis of the substrate is at least three times the intensity polarized perpendicular thereto.
