The present invention provides a high-contrast reflective display and transmissive display with a wide viewing angle in a transflective liquid crystal display device having reflective and transmissive structures. In such a display, each of dots can contain a reflective display region for reflective display and a transmissive display region for transmissive display. A liquid crystal layer can be composed of a nematic liquid crystal aligned substantially perpendicularly to substrates and having a negative dielectric anisotropy. A first retardation film having an optically negative uniaxiality, a second retardation film having an optically positive uniaxiality, and a first polarizer are arranged in that order outside an upper substrate, and a third retardation film having an optically negative uniaxiality, a fourth retardation film having an optically positive uniaxiality, a second polarizer, and illumination means are arranged in that order outside a lower substrate.
