Abstract:
1. A liquid crystal panel comprising: a liquid crystal cell; a first polarizer arranged on one side of the liquid crystal cell; a first birefringent layer arranged between the liquid crystal cell and the first polarizer and on a viewer side of the liquid crystal cell; a second polarizer arranged on another side of the liquid crystal cell; and a second birefringent layer arranged between the liquid crystal cell and the second polarizer; wherein: the first birefringent layer has a relationship of 1<Nz ≦2 where an Nz coefficient is defined by Nz=(nx-nz)/(nx-ny); the first birefringent layer comprises a cyclic olefin-based film; and the second birefringent layer has a refractive index profile of nx=ny>nz.
