Abstract
There is provided a liquid crystal panel having excellent balance between contrast and viewing angle characteristics. A liquid crystal panel according to an embodiment of the present invention includes: a first polarizer; a first optical compensation layer containing a resin having an absolute value of photoelastic coefficient of 2×10m/N or less, and having a relationship of nx>ny=nz; a second optical compensation layer having a relationship of nx=ny>nz; a liquid crystal cell; a third optical compensation layer containing a resin having an absolute value of photoelastic coefficient of 2×10m/N or less, and having a relationship of nx>ny=nz; and a second polarizer, in the stated order forward a viewer side, wherein the sum ΣRthof the thickness direction retardation of all the optical compensation layers and the thickness direction retardation Rthof the liquid crystal cell satisfy the following expression (1):−50 nm<(Σ)<150 nm  (1).
