    • There is provided a retardation film capable of adjusting an angel between a proceeding direction of a film and an optical axis of liquid crystal by employing an alignment layer formed of polymers induing norbornene and improving thermal stability and photoreaction rate, a method for preparing the retardation film and a polarizer comprising the retardation film. The retardation film includes a substrate, an alignment layer formed on the substrate and made of polymers including norbornene, and an alignment layer fixing layer formed on the alignment layer and made of liquid crystal materials; the method for preparing a retardation film includes: forming a polymer layer by coating a substrate with a polymer solution induing norbornene and drying the polymer solution, forming an alignment layer by irradiating the copolymer layer with linearly polarized ultraviolet rays in a predetermined direction relative to a proceeding direction of a film to give an orientation to the copolymer layer, forming a liquid crystal layer on the alignment layer by coating the alignment layer with a nematic liquid crystal solution and drying the nematic liquid crystal solution, and fixing the orientation of the liquid crystal layer by curing the liquid crystal layer; and the polarizer includes the retardation film and a polarizer film, both of which are stacked with each other. The retardation film has improved thermal stability and light reaction speed, and the retardation film whose optical axis has a desired orientation angle relative to a proceeding direction of the retardation film may be easily prepared through the irradiation of polarized ultraviolet rays.
