Abstract:
The liquid crystal panel 1 of the present invention comprises a liquid crystal cell 2, a first polarizer 31 disposed on one surface side of the liquid crystal cell 2, a second polarizer 41 disposed on the other surface side of the liquid crystal cell 2, and first optical compensation layer 5 and second optical compensation layer 6 disposed between the first polarizer 31 and second polarizer 41, and the liquid crystal cell 2 satisfies a relationship of 0.8 Re [450]/Re [550] 1, the first optical compensation layer 5 satisfies relationships of the Nz coefficient is from 0.8 to 1.4 and 0.8 Re[450]/Re[550] 1, and the second optical compensation layer 6 satisfies relationships of nx =ny>nz and 0.98 Re[450]/Re[550] 1.04. The liquid crystal panel of the present invention is hardly generated color shift when the panel is viewed from all azimuth angle directions and polar angle directions, so that the liquid crystal panel is excellent in color display characteristics.
