To provide a polymer film having a high ratio of Rth to Re without causing a planar failure such as bleed out. Furthermore, the present invention provides a liquid crystal display device having a wide viewing angle and high display quality, incorporating a polarizing plate using the above polymer film. A polymer film comprising organic compound fine particles containing a retardation developing agent having an average particle diameter of 1 nm or more and 1000 nm or less. In addition, in the process of casting, stripping and drying a dope containing a polymer, a polymer solvent, a retardation developing agent, etc. on a support, the retardation developing agent is uniformly dissolved in the dope and stretched from casting. A method for producing a polymer film, wherein organic compound fine particles containing a retardation enhancer are formed in the film during the steps up to. [Selection figure] None |
