ABSTRACT:
The present invention provides a method for producing an optical compensating sheet, comprising a step of simultaneously coating at least two coating solutions on a transparent support, wherein at least one of the coating solutions simultaneously coated in that step contains a liquid crystalline compound and another coating solution contains a surface active agent; an optical compensating sheet obtained by this method; an optical film comprising a support having thereon an optically anisotropic layer formed containing a liquid crystalline compound and a fluoroaliphatic group-containing copolymer containing a repeating unit derived from a fluoroaliphatic group-containing (meth)acrylate monomer and a repeating unit derived from a polyoxyalkylene (meth)acrylate monomer; and a polarizing plate and a liquid crystal display device each using the optical compensating sheet or optical film.
