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. 130 nm≦Re[590]≦250 nm (1) 0 nm
