A cyclic polyolefin film, which comprises: a cyclic polyolefin resin; and at least one organic compound decreasing Rth(lambda) and/or at least one organic compound decreasing Re(lambda), wherein Rth(lambda) represents a retardation value (nm) in a thickness-direction of the cyclic polyolefin film at a wavelength of lambda nm, and Re(lambda) represents an in-plane retardation value (nm) of the cyclic polyolefin film at a wavelength of lambda nm, wherein the cyclic polyolefin film comprises the at least one organic compound in a content of from 0.01 to 30% by mass based on a solid component of the cyclic polyolefin resin.
