Abstract
The liquid crystal panelof the present invention comprises a liquid crystal cell, a first polarizerdisposed on one surface side of the liquid crystal cell, a second polarizerdisposed on the other surface side of the liquid crystal cell, and first optical compensation layerand second optical compensation layerdisposed between the first polarizerand second polarizer, and the liquid crystal cellsatisfies a relationship of 0.8 Re [450]/Re [550] 1, the first optical compensation layersatisfies 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 layersatisfies 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.
