POLYMER FILM, RETARDATION FILM, METHOD FOR PRODUCING RETARDATION FILM AND OPTICAL COMPENSATION POLARIZING PLATE BY USING THE RETARDATION FILM

PROBLEM TO BE SOLVED: To provide a retardation film having the larger retardation value as the wave length becomes the longer as a single film and also having ≤±4% changing rate of the in-plane directional retardation value (Re) in width direction. SOLUTION: This polymer film consisting mainly of a...
