PROBLEM TO BE SOLVED: To provide a cellulose acylate film with excellent optical properties low in change of Re (in-plane retardation) and Rth (thickness direction retardation) in a wide wavelength band, and to provide a cellulose acylate film excellent in durability low in change of optical properties, especially low in change of Rth, to saponification treatment, irradiation with light, and to provide an optical material such as a polarizer, etc., composed of the cellulose acylate film low in change of Re and Rth in a wide wavelength band, excellent in durability, and to provide a liquid crystal display with a wide view angle and high quality image using the same. SOLUTION: The invention relates to the cellulose acylate film comprising at least one near-infrared absorber with maximum absorbing wavelength at 700-1200 nm, and at least one specific ultra-violet absorber, and the invention relates to the polarizer plate and the liquid crystal display using the same.
