Disclosed is a method of manufacturing a polarizing plate capable of maintaining high-quality display image quality on a display such as a liquid crystal display device over a long period of time, and a polarizing plate and a liquid crystal display device using the same. A method of manufacturing a polarizing plate in which a first protective film containing a cellulose acylate resin, a polarizer, and a second protective film containing a cycloolefin resin are laminated in this order. One protective film has a moisture permeability of 200 to 1500 g / m 2 / day at 60 ° C. and 95% RH, and the second protective film has a moisture permeability of 0.1 to 10 g / m at 60 ° C. and 95% RH. 2 / day, and the polarizing plate has an orthogonal transmittance of 0.005% or less and a parallel transmittance of 32% or more at 20 ° C. and 98% RH at a wavelength of 480 nm. After bonding the protective film and the second protective film through the adhesive solution, until the water content of the polarizing plate is at least 70% by mass or less of the water content immediately after bonding with the adhesive solution, 40 to 40%. Dry at a temperature of 55 ° C The manufacturing method of a polarizing plate including the process made to dry. [Selection figure] None |
