Abstract
The present invention relates to a polarizing plate, a method for producing the same, and an image display device comprising the same, and more specifically to a polarizing plate which is characterized by comprising: a) a polarizer, b) a hardening resin layer which is provided on at least one side of the polarizer and formed from a photocurable composition comprising: 4 to 95 parts by weight of (A) a photocurable acrylic polymer, 4 to 95 parts by weight of (B) a poly-functional acrylic monomer, and 1 to 20 parts by weight of (C) a photo-polymerization initiator, based on 100 parts by weight of the photocurable composition, a method for manufacturing the same, and an image display device using the same. According to the present invention, a polarizing plate, which exhibits excellent polarizing properties and durability, has high surface hardness, and may be formed as a thin plate, may be provided.
