摘要： A liquid crystal display apparatus of the present invention includes: a liquid crystal cell including a pair of substrates provided with a color filter on one substrate, and a liquid crystal layer as a display medium provided between the substrates; and an optical compensation element including at least an optical compensation layer. The optical compensation element is arranged on the same side as the color filter with respect to the liquid crystal layer. The substrate provided with the color filter preferably has a haze value of 10% or less. Such a liquid crystal display apparatus allows excellent viewing angle compensation, exhibits exceptional contrast in an oblique direction, and can be reduced in thickness.

摘要： A method for producing an optical film including a birefringent layer having a refractive index distribution satisfying nx>nz>ny that can be produced by a small number of steps, contains less foreign matter trapped therein, and has high productivity. The method includes steps of: forming a coating film by directly applying a material for forming a birefringent layer on the shrinkable film; shrinking the coating film in a first direction by shrinking the shrinkable film; and stretching a laminate of the shrinkable film and the coating film in a second direction orthogonal to the first direction, wherein the material for forming a birefringent layer contains at least one resin selected from norbornene resins, polycarbonate resins, cellulose resins, polyamides, and polyurethanes, and wherein the birefringent layer has a refractive index distribution satisfying nx>nz>ny. An optical film produced by the method.
