ABSTRACT:
A positive uniaxial film14with a retardation of Rp [nm] in an in-plane direction is disposed between a vertical alignment mode liquid crystal cell11and a polarizing plate12, and a negative uniaxial film15with a retardation of Rn [nm] in a thickness direction is disposed between the positive uniaxial film14and the polarizing plate12. Further, when a parameter α1 [nm] in relation to Rp is 35+(Rlc/80−4)2×3.5+(360−Rlc)×Rtac/850; and a parameter β1 [nm] in relation to Rn is Rlc−1.9×Rtac, where Rtac [nm] is a retardation in a thickness direction of the respective base films of polarizing plates12and13, the retardations Rp and Rn are set to fall within ranges of 80% to 120% of the parameter α1and 60% to 90% of the parameter β1, respectively.
