| 主权项 | 1. A liquid crystal display device comprising a liquid crystal cell and a polarizer arranged on at least one outer side of the liquid crystal cell, wherein: the liquid crystal cell includes a pair of substrates at least one of which has an electrode and which are arranged oppositely to each other, and a liquid crystal layer sandwiched between the substrates, and at least one substrate includes at least three color pixels of pixels of blue, green and red satisfying the following formula (1-1), and the polarizer includes a polarizing element and a film satisfying the following formula (1-2) and containing an optically-anisotropic layer: (1-1)−20 nm<={Rth[cell] (630)−Rth[cell] (440)}<=28 nm, wherein Rth[cell] (lambda) means the thickness-direction retardation of the liquid crystal cell when a light having a wavelength λ passes through at least one of the at least three color pixels of the cell; (1-2) 1 nm<Re(630)−Re(440)<=12 nm, wherein Re(630) means the in-plane retardation of the film at a wavelength of 630 nm, and Re(440) means the in-plane retardation thereof at a wavelength of 440 nm. | ||
