PROBLEM TO BE SOLVED: To provide an OCB mode liquid crystal display device with which heightening of contrast and widening of a viewing angle are materialized by optimizing a construction of a PDM compensation film and a condition of bend alignment of a liquid crystal without depending on trial-and-error methods, in an OCB-LCD using the PDM compensation film. SOLUTION: The OCB mode liquid crystal display device using the PDM compensation film is constructed in such a way that a polarization state of light after passing through a biaxial substrate 2 turns into elliptically polarized light having an elliptical longitudinal direction of about 45°or about -45°with respect to an incident plane (a biaxial substrate 8 similarly functions) in an orientation plane of a bend aligned liquid crystal 5 or in a plane vertical thereto without being influenced by an incident angle.
