A positive uniaxial film 14 with a retardation of Rp [nm] in an in-plane direction is provided between a vertical alignment mode liquid crystal cell 11 and a polarizing plate 12, and a negative uniaxial film 15 with a retardation of Rn [nm] in a thickness direction is provided between the liquid crystal cell 11 and a polarizing plate 13. Further, when a parameter .alpha.1 [nm] relative to Rp is: .alpha.1=135-0.7.times.Rtac; and a parameter .beta.1 [nm] relative to Rn is: .beta.1=Rlc-65-1.4.times.Rtac, where Rtac [nm] is a retardation in a thickness direction of the respective triacetyl cellulose films 12b and 13b of polarizing plates 12 and 13, the retardations Rp and Rn are set to be values greater than 90% but smaller than 110% with reference to the parameters .alpha.1 and .beta.1, respectively. This makes it possible to surely provide a vertical alignment mode liquid crystal display device which can maintain a high contrast when viewed from an oblique direction.
