Abstract:
A liquid crystal display device comprising:a liquid crystal display element, which includes a pair of transparent substrates provided with alignment films on respective facing surfaces thereof, and a liquid crystal layer filling a space between said transparent substrates; a pair of polarizers, one provided in each side of said liquid crystal display element; at least one optical retardation plate, provided between said liquid crystal display element and one of said polarizers, having an index ellipsoid which inclines; wherein said alignment films align liquid crystal molecules of said liquid crystal layer in a different direction in each of a plurality of liquid crystal layer divisions of unequal area into which each pixel is divided; and wherein said liquid crystal layer and said at least one optical retardation plate are set such that a relationship (Î”&it;â€ƒ&it;nL&af;(Î»1)/Î”&it;â€ƒ&it;nL&af;(Î»2))-1(Î”&it;â€ƒ&it;nF&af;(Î»1)/Î”&it;â€ƒ&it;nF&af;(Î»2))-1is set within a range such that viewing-angle-dependent coloring of an image displayed on said liquid crystal element does not occur, where &Dgr;nL(&lgr;1) is anisotropy of the refractive index of said liquid crystal material of said liquid crystal layer in response to light having a wavelength of &lgr;1, &Dgr;nL(&lgr;2) is anisotropy of the refractive index of said liquid crystal material of said liquid crystal layer in response to light having a wavelength of &lgr;2, &Dgr;nF(&lgr;1) is anisotropy of the refractive index of said at least one optical retardation plate in response to light having a wavelength of &lgr;1, and &Dgr;nF(&lgr;2) is anisotropy of the refractive index of said at least one optical retardation plate in response to light having a wavelength of &lgr;2.
