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.
