ABSTRACT:
A liquid crystal panel of this invention has a first polarizer and a second polarizer disposed on both sides of a liquid crystal cell, and a first optical compensation layer disposed between the liquid crystal cell and the first polarizer, a second optical compensation layer disposed between the liquid crystal cell and the second polarizer, and a third optical compensation layer disposed between the first optical compensation layer and the second optical compensation layer, and wavelength dispersion of the liquid crystal cell satisfies Re40(450)>Re40(550)>Re40(650), wavelength dispersion of the first optical compensation layer and wavelength dispersion of the second optical compensation layer satisfy 0.7<Re40(450)/Re40(550)<1.05, and wavelength dispersion of the third optical compensation layer satisfies Re40(450)>Re40(550)>Re40(650).
