1. A laminated optical film, comprising:
a polarizing plate; and a retardation layer comprising a water dispersible pressure-sensitive adhesive composition containing an inorganic laminar compound; wherein the retardation layer has a thickness direction birefringence index Δnxz of 0.002 to 0.02; and wherein a content of the inorganic laminar compound in the retardation layer is 30 to 200 parts by weight with respect to 100 parts by weight of a resin solid content; wherein a resin component in the water dispersible pressure-sensitive adhesive composition comprises at least one resin selected from the group consisting of a (meth)acrylic resin, a polyurethane-based resin, a polyester-based resin, a phenol resin, an ethylene-vinyl acetate resin, an epoxy resin, and a silicone resin; and wherein the water dispersible pressure-sensitive adhesive composition is an emulsion of a polymer.
