FILM AND METHOD FOR PRODUCING SAME, POLARIZING PLATE USING SAME, AND LIQUID CRYSTAL DISPLAY

摘要

Disclosed is a film which is improved in curling and suitable for a polarizing plate in the form of a thin film. Also disclosed are a method for producing such a film, a polarizing plate using such a film, and a liquid crystal display. Specifically disclosed is a film to be bonded to a polarizer of a polarizing plate. This film is characterized in that it has a thickness of not less than 10 mum and not more than 70 mum. This film is also characterized in that it has a surface A and a surface B opposite to the surface A, and the refractive index difference between the surface A and the opposing surface B is not less than 5 x 10-4 and not more than 5 x 10-3.
