发明名称 POLARIZING PLATE
摘要 PROBLEM TO BE SOLVED: To provide a polarizing plate, in which a polypropylene resin film to which ultraviolet ray cut performance is imparted by addition of an ultraviolet absorber is laminated at least on one side of a polarizing film via an adhesive layer, and the adhesive strength between the polypropylene resin film and the polarizing film is fully high.SOLUTION: The polarizing plate is obtained, by sticking transparent resin films to both sides of the polarizing film consisting of a polyvinyl alcohol resin via adhesives, respectively. The transparent resin films to be stuck to both the surfaces of the polarizing film have moisture vapor transmission, at 40 °C of 50g/mor less per day or less, and at least one of the transparent resin films to be stuck to the both sides of the polarizing film is the polypropylene series resin film, containing the ultraviolet absorber whose molecular weight is ≥450 in an amount of 0.1 to 1.5 wt.%.
