Abstract:
1. A liquid crystal display device, comprising: a first polarizer; a second polarizer; a liquid crystal cell; a first birefringent layer; and a second birefringent layer, the second polarizer having an absorption axis orthogonal to an absorption axis of the first polarizer, the liquid crystal cell being disposed between the first polarizer and the second polarizer, the first birefringent layer being disposed between the first polarizer and the liquid crystal cell, satisfying 0.6≦Nz(550)≦6, and having an in-plane slow axis orthogonal to the absorption axis of the first polarizer, the second birefringent layer being disposed between the liquid crystal cell and the second polarizer, satisfying −5≦Nz(550)≦0.4, and having an in-plane slow axis parallel to the absorption axis of the second polarizer, and at least one of the first and second birefringent layers satisfying |Rxy(450)|≦|Rxy(550)|≦|Rxy(650)|.
