Patent ID: 7697095

Claim:
A liquid crystal display device comprising: a first polarizing element and a second polarizing element which are disposed with their transmission axes perpendicular to each other, a liquid crystal layer disposed between the first and the second polarizing elements, and a first optically anisotropic layer disposed between the first or the second polarizing element and the liquid crystal layer, showing a positive in-plane retardation (Re) at λ1 and a negative Re at λ2, both of λ1 and λ2 (λ1≠λ2) are within a visible wavelength range, and its absolute value of a thickness-direction retardation at 550 nm, |Rth(550)|, is equal to or more than 50 nm, wherein the first optically anisotropic aver satisfies relations (1) and (2): Re (450)× Re (650)<0 (1) | Rth (550)/ Re (550)|>10 (2) wherein Re(λ) means an in-plane retardation (unit; nm) measured applying light having a wavelength of λ nm to the layer, and the positivity and the negativity of Re is decided with reference to an absorption axis of the first and second polarizing element which is disposed nearer to the layer than another, and the direction parallel to the absorption direction is a positive direction.
