POLARIZING PLATE WITH POLYETHYLENE TEREPHTHALATE FILM AS PROTECTIVE FILM, AND METHOD FOR MANUFACTURING SAME
First Claim
1. A polarizing plate comprising:
- a water-based adhesive layer, a primer layer, and a polyethylene terephthalate protection film sequentially provided on at least one surface of a polarizer,wherein the water-based adhesive layer is formed by using a water-based adhesive including a polyvinyl alcohol-based resin and a glyoxalate crosslinking agent at a weight ratio of 100;
5 to 100;
50, and the primer layer is formed by using a primer composition including a polyester-based compound and an acryl-based compound.
