CELLULOSE ACYLATE FILM AND METHOD FOR PRODUCING SAME, AND RETARDATION FILM, POLARIZER AND LIQUID CRYSTAL DISPLAY DEVICE COMPRISING THE FILM

摘要

A cellulous acylate film in which X-ray diffractive intensity satisfies the following Formulae (I) to (V) and in which a half-value width of the peak at 2Theta2 is 2.8°or less as observed in the sectional view in a direction parallel to the transport direction of the film: Formula (I): 0.60 Ici/Ico Formula (II): Iam = IX+{(I3-Ii)/(2Theta3-2Thetai)}x(2Theta2-2Thetai) Formula (III): Ic = I2-Iam Formula (IV): Ici = Icn/Ici2 Formula (V): Ic0 ={(Ic2i/Ic22)+(Ic31/Ic32)}/2.
