摘要:
A laminated film includes a polarizing plate, a retardation film, and a first pressure-sensitive adhesive layer provided in this order, wherein the polarizing plate includes a polarizer, a first protective layer placed on a side of the polarizer where the retardation film is provided, and a second protective layer placed on another side of the polarizer which is opposite to the side where the retardation film is provided, the retardation film is a stretched film comprising a norbornene resin, the first pressure-sensitive adhesive layer includes a pressure-sensitive adhesive that may be produced by crosslinking a composition comprising a (meth)acrylate (co)polymer and a crosslinking agent comprising a peroxide as a main component. The laminated film has both good adhesion to a liquid crystal cell and easy peelability, and may improve the uniformity in a screen of liquid crystal display.
