摘要： An object of the present invention is to provide a method for manufacturing an optical laminate in which an alignment defect is less likely to occur in a light-absorbing anisotropic layer even in a case where a surface of a photo-alignment layer is rubbed; an optical laminate; and an image display device. The method for manufacturing an optical laminate according to an embodiment of the present invention is a method for manufacturing an optical laminate in which an optical laminate including a photo-alignment layer and a light-absorbing anisotropic layer and having a front transmittance of 60% or less is produced and which includes a photo-alignment layer formation step of forming a photo-alignment layer on a polymer film, and a light-absorbing anisotropic layer formation step of applying a liquid crystal composition containing a dichroic substance and a high-molecular liquid crystalline compound onto the photo-alignment layer to form a light-absorbing anisotropic layer.

摘要： 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.
