    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≦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 40×10−12 (m2/N) or less, and has relationships of Δnd(380) 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.

    摘要: A polarizing plate of the invention comprises a polarizer; and a transparent protective film provided on at least one side of the polarizer with an adhesive layer interposed therebetween, wherein the adhesive layer is formed of an adhesive for polarizing plate comprising: a resin solution comprising a polyvinyl alcohol-based resin, a crosslinking agent and a colloidal metal compound with an average particle size of 1 nm to 100 nm, wherein 200 parts by weight or less of the colloidal metal compound is added to 100 parts by weight of the polyvinyl alcohol-based resin, and the transparent protective film provided on at least one side is a retardation plate having a front retardation of 40 nm or more and/or a thickness direction retardation of 80 nm or more. The polarizing plate can reduce the occurrence of knicks.
