Method for manufacturing a retardation film, the phase difference film, polarizing plate and a liquid crystal display

摘要

Retardation film containing a polymer having a vinyl carbazole structure excellent haze, adhesion, suitability roll conveyor, reworkability polarizer, the front contrast, the manufacturing method of the retardation film, an object of the present invention, the retardation film It is another object of the present invention to provide a liquid crystal display device and a polarizing plate was used. A retardation film obtained by laminating the layers A and B, the A layer is a layer containing a polymer containing a carbazole structural unit, and a crosslinked product of a vinyl monomer, the retardation film of the present invention, B The layer is characterized in that it is a layer made of a heat-friendly resin.
