Abstract: A liquid crystal display apparatus is provided in which light leakage from a peripheral portion of a non-selected pixel can be suppressed without reducing the aperture ratio of each pixel, and the contrast can be improved.

Abstract: A vertically aligned liquid crystal display device is provided in which the phase difference value is increased be-yond a usual range, whereby the ON transmittance in high duty driving is increased to improve the contrast and the viewing angle. In the vertically aligned liquid crystal display device, the phase difference value in the thickness direction of the liquid crystal layer 8 is set in a range of from 500 nm to 1,600 nm, and a first phase difference plate 13 is inserted between the first and second polarizing plates 9, 10 in which the absorption axes 9a and 10a per-pendicularly intersect with each other. The first phase difference plate 13 is a uniaxial phase difference plate which has a negative refractive index anisotropy, in which the phase difference value in the thickness direction is set in a range of from 220 nm to 1,320 nm, and which has the optical axis perpendicular to first and second glass substrates 4,5 between which a liquid crystal layer 8 is interposed.

Abstract: A vertically aligned liquid crystal display device is provided in which the phase difference value in the thickness direction of a liquid crystal layer is increased beyond a usual range, whereby the ON transmittance in high duty driving is increased to improve the contrast and the viewing angle.

Abstract: A TN type liquid crystal cell is interposed between a pair of polarization plates. First and second retardation films each having slow axes orthogonal to each other are disposed between one of the polarization plates and the liquid crystal cell. The product .DELTA.n.sub.1 .times.d.sub.1 of the refractive index anisotropy .DELTA.n.sub.1 and the thickness d.sub.1 of the first retardation film on the side of one of the polarization plates is set to a value greater than the product .DELTA.n.sub.2 .times.d.sub.2 of the refractive index anisotropy .DELTA.n.sub.2 and the thickness d.sub.2 of the second retardation film. The viewing angle of the liquid crystal display panel in the left-right direction is expanded by this arrangement.
