Polarizing plate, method for manufacturing same, and image display device comprising same

A method for manufacturing a polarizing plate by forming a first protective layer and a second protective layer in this sequence on at least one surface of a polarizer, the method comprising:

• applying a radical curable composition on at least one surface of a polarizer;
• forming a first protective layer by irradiating an active energy ray on the applied radical curable composition to cure the radical curable composition by radical polymerization;
• applying a cationic curable composition on a surface opposite to a surface adjacent to a polarizer of the first protective layer;
• and
• forming a second protective layer by irradiating an active energy ray on the first protective layer and the cationic curable composition applied thereon to cure both the first protective layer and the cationic curable composition by cationic polymerization.
