发明名称 Liquid crystal panel and liquid crystal display apparatus
摘要 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≦̸&Dgr;nd (550)≦̸10 nm and 0 nm≦̸Rth(550)≦̸20 nm. The first optical compensation layer has an absolute value of a photoelastic coefficient of 40×10−12 (m2/N) or less, and has relationships of &Dgr;nd(380)<&Dgr;nd(550)<&Dgr;nd(780), nx>ny≧nz and 90 nm≦̸&Dgr;nd(550)≦̸200 nm. The second optical compensation layer has relationships of Rth(380)>Rth(550)>Rth(780) and nx=ny>nz.
