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.

Method for manufacturing polarizing plate

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.

Optical film

Disclosed is a polarizing plate including a polarizing film and a protective film provided on the polarizing film, and a display device having the same.

Polarizing plate and display device comprising same

Provided are a polarizing plate including a polarizing film and protective films provided on both sides of the polarizing film and a display device including the same.
