Abstract | A method for producing a photostable reactive mesogen alignment layer includes infusing an anisotropic dye into a microcavity so as to coat the an surface of the microcavity with the anisotropic dye; illuminating the anisotropic dye with polarized light so as to form an anisotropic dye layer aligned with respect to the inner surface of the microcavity; infusing a reactive mesogen and the liquid crystal material into the microcavity; illuminating the reactive mesogen at a wavelength selected to cause polymerization of the layer of the reactive mesogen so as to form a polymerized reactive mesogen layer; aligning the liquid crystal material with respect to the anisotropic dye layer; and bleaching the anisotropic dye layer. |
