A method for manufacturing a polarizing plate, the method comprising bonding a first transparent protective film and a second transparent protective film to both sides of a polarizer with an adhesive layer interposed between the polarizer and each of the first and second transparent protective films, wherein the first and second transparent protective films have different elasticities (elastic modulus×thickness (μm)), the three films are pressure-bonded by being simultaneously allowed to pass between a pair of rolls, a direction in which the polarizer is fed and allowed to pass between the pair of rolls is inclined toward the high-elasticity film. The polarizing plate obtained by the method can be suppressed the occurrence of bubbles between the polarizer and the transparent protective films.
