发明名称 Liquid crystal panel and liquid crystal display apparatus
摘要 There is provided a liquid crystal panel having an improved contrast ratio in an oblique direction and an improved color shift in an oblique direction. Further, there is provided a liquid crystal panel with excellent display uniformity. The liquid crystal panel of the present invention includes: a liquid crystal cell; a first polarizer arranged on one side of the liquid crystal cell; a second polarizer arranged on the other side of the liquid crystal cell; a first optical element and a second optical element arranged between the first polarizer and the liquid crystal cell; and a third optical element arranged between the second polarizer and the liquid crystal cell, in which: the first optical element has substantially optically negative uniaxial property; the second optical element satisfies the following expressions (1) and (2) and is arranged between the first optical element and the liquid crystal cell; and the third optical element has substantially optical isotropy. <?in-line-formulae description="In-line Formulae" end="lead"?>130 nm<=Re[590]<=250 nm (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>0 nm<Rth[590]<Re[590].
