Claim:
A liquid crystal display comprising: a liquid crystal cell of VA mode; and a polarizing plate, the polarizing plate comprising: a polarizer; and a protective film comprising a cellulose acylate film having a thickness of 40 to 180 μm and containing no retardation increasing agent, wherein the cellulose acylate film has a retardation value Re in a film plane thereof and a retardation value Rth in a direction perpendicular to the film plane, the retardation values Re and Rth being defined by formula (I) and (II), respectively, and the retardation values Re and Rth measured at 25° C. and 60% RH satisfy formula (III) to (V): Re =( nx−ny )× d (I) Rth ={( nx+ny )/2 −nz}×d (II) 46≦Re≦100 (III) Rth=a− 5.9 Re (IV) 520≦a≦670 (V) wherein the retardation values Re and Rth are values by nm at a wavelength of 590 nm, nx is a refractive index in a slow axis direction in the film plane, ny is a refractive index in a fast axis direction in the film plane, nz is a refractive index in the direction perpendicular to the film plane, and d is a thickness by nm of the cellulose acylate film, wherein retardation values Re (λ) and Rth (λ) measured at 25° C. and 60% RH, which are the retardation values Re and Rth at a wavelength of λ nm, respectively, satisfy relations (A) and (B): 0.80 ≦Re (450) /Re (550) ≦1.00 and 1.00 ≦Re (650) /Re (550) ≦1.20 (A) 0.90 ≦Rth (450) /Rth (550) ≦1.00 and 1.00 ≦Rth (650) /Rth (550) ≦1.10 (B), wherein the polarizing plate satisfies at least one of formulae (j) and (k): −6.0≦ΔCT≦6.0 (j) −10.0≦ΔP≦0.0 (k) wherein ΔCT and ΔP represents a change in cross transmittance and polarization degree, respectively, in a test that the polarizing plate is allowed to stand at 60° C. and 95% RH for 500 hours; and the change means a value calculated by subtracting a measurement value before the test from a measurement value after the test.
