Abstract:
1. A liquid crystal display panel, comprising: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; a second polarizing plate placed on another 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 having absorption axes whose directions are substantially orthogonal to each other; the retardation film being a norbornene resin-containing stretched film and having a refractive index ellipsoid satisfying the relation nx≧nz>ny, wherein nx is a refractive index in a slow axis direction, ny is a refractive index in a fast axis direction, and nz is a refractive index in a thickness direction; the retardation film is obtained by bonding a shrinkable film to both sides of a polymer film containing the norbornene resin and heating and stretching the laminate; and the pressure-sensitive adhesive layer comprising a pressure-sensitive adhesive that has a gel fraction of 40% to 90% and is produced by crosslinking a composition comprising a (meth)acrylate (co)polymer and a crosslinking agent comprising a diacyl peroxide as a main component.
