Abstract: The present disclosure relates to a method for manufacturing a polarizing plate. The method includes a step of preparing a transfer type retarder laminate which has a carrier substrate, an alignment film and a retarder layer sequentially; and a step of laminating the transfer type retarder laminate on one side of a polymeric stretched film containing a dichroic substance, where a peel force at a peeling angle of 90° between the carrier substrate and the retarder layer in the transfer type retarder laminate and a peeling rate of 300 mm/min is in a range of 0.10 N/20 mm to 0.13 N/20 mm. The polarizing plate can be used as a circularly polarizing plate or an optical compensation polarizing plate in various display devices.

Abstract: Provided are a liquid crystal composition, a liquid crystal film and a display device. The liquid crystal composition according to the present application may form a liquid crystal layer in which staining due to a thickness difference does not occur even in large-area coating such that a liquid crystal layer can be formed on a base layer having erosivity to a raw material since the liquid crystal composition may have a suitable solubility even in a solvent in which solubility is normally low.
Abstract translation: 提供液晶组合物，液晶膜和显示装置。 根据本申请的液晶组合物可以形成液晶层，其中即使在大面积涂布中也不会发生由于厚度差异而导致的染色，使得可以在具有对原始图案的侵蚀性的基底层上形成液晶层 因为液晶组合物即使在溶解度通常较低的溶剂中也可以具有合适的溶解度。
