Claim 11:
12. The liquid crystal display device according to claim 3,
wherein a second optically anisotropic layer including a positive A plate satisfying relationships of Expression (7) and Expression (8) and a positive C plate satisfying relationships of Expression (9) and Expression (10) is provided in at least between the first polarizer and the liquid crystal cell or at least between the second polarizer and the liquid crystal cell,

80 nm≤ReA(550)≤160 nm  Expression (7)

0.75<ReA(450)/ReA(550)<1.00  Expression (8)

−160 nm≤RthC(550)≤−60 nm  Expression (9)

0.75<RthC(450)/RthC(550)<1.00  Expression (10)

ReA(550) represents an in-plane retardation of the positive A plate at a wavelength of 550 nm, ReA(450) represents an in-plane retardation of the positive A plate at a wavelength of 450 nm, RthC(550) represents a thickness direction retardation of the positive C plate at a wavelength of 550 nm, and RthC(450) represents a thickness direction retardation of the positive C plate at a wavelength of 450 nm.
