An elliptically polarizing plate including: a polarizer; and an optical
film that includes a laminate of: a retardation film A that includes a
cyclic polyolefin resin-containing thermoplastic polymer and has
uniaxially-aligned positive refractive-index anisotropy characterized by
nx>ny.apprxeq.nz; and a retardation film B that is fixed to
homeotropic alignment and has positive refractive-index anisotropy
characterized by nz1>nx1.apprxeq.ny1, wherein the optical film is
laminated on one side of the polarizer in such a manner that a slow axis
of the retardation film A is perpendicular to an absorption axis of the
polarizer. The elliptically polarizing plate can suppress a reduction in
contrast at wide viewing angles when applied to in-plane switching mode
active matrix liquid crystal displays, and can be highly effective for
improvements against color shift.
