    摘要: A liquid crystal (LC) display device uses a phase difference film which increases front contrast of the device, and a polarization plate. The film includes a first optical anisotropic layer, and a second optical anisotropic layer thereon, the first layer formed by fixing an LC compound in a homogeneous alignment state, has an order parameter (OP) of 0.75 to 0.95, and layer thickness of 0.3 μm to 3.0 μm, the second layer formed by fixing an LC compound in a homeotropic alignment state, has an OP of 0.60 to 0.95, and layer thickness of 0.3 μm to 3.0 μm, the OP which is denoted by OP=(A∥−A⊥)/(2A⊥+A∥), “A∥” which represents absorbance of the LC compound regarding light polarized parallel to an alignment direction, and “A⊥” which represents absorbance of the LC compound regarding light polarized vertical to the alignment direction.
