Cyclic polyolefin film having low hygroscopicity and moisture permeability, little change in optical properties due to temperature and humidity changes, little optical unevenness, and optical properties capable of independently controlling Rth (λ) and Re (λ). To provide. To provide a polarizing plate or a liquid crystal display device having excellent film forming stability and processing characteristics and having no image unevenness. A cyclic polyolefin film comprising at least one polyester polymer in a cyclic polyolefin, A cyclic polyolefin film with reduced retardation Rth in the film thickness direction.
