A transflective liquid crystal display device is provided which is bright in the transmission mode, high in contrast, designable to be thin, and less dependence on the viewing angle. The transflective liquid crystal display comprises a first substrate having a transparent substrate, a second substrate having a transflective electrode, a nematic liquid crystal layer sandwiched therebetween, a first optical anisotropic element disposed on the first substrate, a polarizer disposed on the first optical anisotropic element, a second optical anisotropic element disposed on the first substrate, and a polarizer disposed on the second optical anisotropic element wherein the first optical anisotropic element comprises a phase difference film fulfilling the specific requirements and the second optical anisotropic element is formed with a liquid crystalline polymeric substance exhibiting positive uniaxial properties.
