LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY APPARATUS
摘要:
An object of the present invention is to provide a liquid crystal panel and a liquid crystal display apparatus which can contribute to the reduction in thickness, realize a high contrast while enhancing viewing angle characteristics, suppress a color shift, and satisfactorily prevent the light leakage in a black display. A liquid crystal panel of the present invention 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) 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) 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; 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; and the first optical compensation layer and the second optical compensation layer, and the third optical compensation layer and the fourth optical compensation layer are placed in a symmetric positional relationship with respect to the liquid crystal cell.
