Patent ID: 7976914

Claim:
A liquid crystal display device comprising: a liquid crystal cell; and two polarizing plates, between which the liquid crystal cell is sandwiched, and each of which comprises: a polarizer; and two protective films, between which the polarizer is sandwiched, wherein one of two protective films on the liquid crystal cell side of the four protective films is a resin film having: a photoelastic coefficient of from 0 to 30×10 −8 cm 2 /N; and Re satisfying the following formulae (1) to (4): 20 nm<Re (548)<300 nm Formula (1) 0.5 <Re (446)/ Re (548)<1 Formula (2) 1.0 <Re (629)/ Re (548)<2.0 Formula (3) 0.1%≦[{ Re (548) at 25° C., 10% RH−Re (548) at 25° C., 80% RH}/Re (548) at 25° C., 60% RH]≦ 20%, Formula (4) wherein Re(λ) represents an in-plane retardation at a wavelength of λ, and the other of two protective films on the liquid crystal cell side of the four protective films satisfies the following formulae (8) to (12): 0 nm< Re (548)<10 nm Formula (8) 100 nm< Rth (548)<300 nm Formula (9) 10 <Rth (548)/ Re (548) Formula (10) 1.0 <Rth (446)/ Rth (548)<2.0 Formula (11) 0.5 <Rth (629)/ Rth (548)<1.0, Formula (12) wherein Re(λ) represents an in-plane retardation at a wavelength of λ, and Rth(λ) represents a retardation in a thickness-direction at a wavelength of λ.
