ABSTRACT:
A liquid crystal panel includes a liquid crystal cell having a liquid crystal layer containing liquid crystal molecules that are vertically aligned in an absence of a voltage; a first optical compensation layer having a relationship of Nz =1 to 2.5 and a relationship of Re1(380) <Re1(550) <Re1(780); a second optical compensation layer having a relationship of nx =ny >nz and a relationship of Re2(380) >Re2(550) >Re2(780); a first polarizer; a third optical compensation layer having a relationship of Nz =1 to 2.5 and a relationship of Re3(380) <Re3(550) <Re3(780); a fourth optical compensation layer having a relationship of nx =ny >nz and a relationship of Re4(380) >Re4(550) >Re4(780); and a second polarizer wherein: the first optical compensation layer, the second optical compensation layer, and the first polarizer are placed on one side of the liquid crystal cell; and the third optical compensation layer, the fourth optical compensation layer, and the second polarizer are placed on the other side of the liquid crystal cell.
