摘要： 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.

摘要： The present application provides an optical film. By controlling transmittance of a liquid crystal layer comprising a radical initiator for the maximum absorption wavelength of the radical initiator, the present application can provide an optical film having a liquid crystal layer having excellent resistance to external stimuli and excellent optical properties. Such an optical film can have various forms and can be used in various fields.
