Disclosed is a method of manufacturing a polarizing plate safe in operation, less burdensome on the environment, and with excellent adhesion to a polarizer; also disclosed are a polarizing plate manufactured using said method, and a liquid crystal display device using said polarizing plate. In the method of manufacturing a polarizing plate, a polarizing plate is manufactured in which a protective film which is hydrophilization-treated by means of alkali saponification is bonded to at least one surface of the polarizer. In the method, said protective film contains cellulose acetate, and the surface free energy before alkali saponification of said protective film fulfills equation (SI), below, and the surface free energy after alkali saponification fulfills equation (SII), below. Equation (SI): 0.25 γ γ sh/γ sp γ 0.40; Equation (SII): 1.5 γ γ sh/γ sp γ 3.0 (wherein ?sh represents the hydrogen bond component of the surface free energy, and ?sp represents the dipole component). |
