    摘要： A liquid crystal display panel includes a liquid crystal cell, a first polarizing plate placed on one side of the liquid crystal cell, a second polarizing plate placed on the other side of the liquid crystal cell, a retardation film placed between the liquid crystal cell and the first polarizing plate, and a pressure-sensitive adhesive layer placed between the liquid crystal cell and the retardation film, wherein the first and second polarizing plates have absorption axes whose directions are substantially orthogonal to each other, the retardation film is a norbornene resin-containing stretched film and has a refractive index ellipsoid satisfying the relation nx≧nz>ny, and the pressure-sensitive adhesive layer includes a pressure-sensitive adhesive that may be produced by crosslinking a composition including a (meth)acrylate (co)polymer and a crosslinking agent including a peroxide as a main component. When the liquid crystal display panel is viewed from oblique directions, leakage of light and changes in color are small, and when the liquid crystal cell is recycled, the laminated film has a high level of easy peelability.
