Abstract
[Object] The present invention provides a liquid crystal panel with which a display with extremely small change in color depending on a viewing direction can be realized, and a liquid crystal display including the same. [Solution to Problem] The liquid crystal panel includes: a first polarizer; a second polarizer; a first optical compensation layer; a second optical compensation layer; and a liquid crystal cell. The first polarizeris arranged on one surface of the liquid crystal cell. The second polarizeris arranged on the other surface of the liquid crystal cell. The first optical compensation layeris arranged between the liquid crystal celland the first polarizer. The second optical compensation layeris arranged between the liquid crystal celland the second polarizer. The first optical compensation layersatisfies the following mathematical formulae (1) and (2). The second optical compensation layer satisfies the following mathematical formulae (3) and (4).  (1)([450]/[550])<1.00  (2)  (3)([450]/[550])≧1.10  (4)
