Patent ID: 8792071

Claim:
A cellulose acylate film comprising a cellulose acylate having a total degree of substitution of from 1.5 to 2.6 and a sugar ester compound, satisfying the following formula (1) and formula (2), having a film thickness of from 20 to 45 μm, having an internal haze of from 0.005 to 0.07%, and having an Rth(550)/d of 3.7 or more: 40 nm≦ Re (550)≦60 nm (1) 100 nm≦ Rth (550)≦300 nm (2) wherein Re(550) means an in-plane retardation (nm) of the film at a wavelength of 550 nm, Rth(550) means a thickness-direction retardation (nm) of the film at a wavelength of 550 nm and d means the film thickness (μm).
