VERFAHREN ZUR AUSRICHTUNG EINES FLÜSSIGKRISTALLMEDIUMS |
摘要 |
Disclosed is a process for aligning the molecules in a liquid crystal medium having a surface adjacent to a substrate, in which the liquid crystals have a molecular weight of less than 1500, and anisotropically absorbing molecules in the medium or in the substrate adjacent to it are exposed to linearly polarized light of a wavelength within the absorption band of the absorbing molecules, and alignment of the liquid crystal medium at an angle + or - theta with respect to the direction of the linear polarization of the incident light beam is induced by the exposed anisotropically absorbing molecules. |
