Abstract
There are provided a liquid crystal panel and a liquid crystal display apparatus each having an excellent screen contrast, a small color shift, and small display unevenness. The liquid crystal panel includes a liquid crystal cell, a first polarizer, a second polarizer, a protective layer, a first optical compensation layer and a second optical compensation layer. The protective layer has relationships of 0 nm≦Δnd (550)≦10 nm and 0 nm≦Rth(550)≦20 nm. The first optical compensation layer has an absolute value of a photoelastic coefficient of 40×10(m/N) or less, and has relationships of Δnd(380)<Δnd(550)<Δnd(780), nx>ny≧nz and 90 nm≦Δnd(550)≦200 nm. The second optical compensation layer has relationships of Rth(380)>Rth(550)>Rth(780) and nx=ny>nz.
