An optically-compensatory film comprising: a cyclic polyolefin film satisfying expression (I); and a cellulose acylate film satisfying expressions (II) and (III), or a liquid-crystal display device comprising at least one cyclic polyolefin film satisfying expression (I) and at least one cellulose acylate film satisfying expressions (II) and (III): 35≦̸Re(630)≦̸350 and 70≦̸Rth(630)≦̸400,  (I) 0≦̸Re(630)≦̸10 and |Rth(630)|≦̸25, and  (II) |Re(400)−Re(700)|≦̸10 and |Rth(400)−Rth(700)|≦̸35,  (III) wherein Re(λ) represents an in-plane retardation value (unit: nm) at a wavelength of λ nm; and Rth(λ) represents a thickness-direction retardation value at a wavelength of λ nm. |
