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 30; a second polarizer 50; a first optical compensation layer 60; a second optical compensation layer 70; and a liquid crystal cell 40. The first polarizer 30 is arranged on one surface of the liquid crystal cell 40. The second polarizer 50 is arranged on the other surface of the liquid crystal cell 40. The first optical compensation layer 60 is arranged between the liquid crystal cell 40 and the first polarizer 30. The second optical compensation layer 70 is arranged between the liquid crystal cell 40 and the second polarizer 50. The first optical compensation layer 60 satisfies the following mathematical formulae (1) and (2). The second optical compensation layer satisfies the following mathematical formulae (3) and (4). nx>ny≧nz (1) (Re[450]/Re[550]) nz (3) (Rth[450]/Rth[550])≧1.10 (4)
