Abstract:
A liquid crystal display device comprising:an STN liquid crystal element comprised of 200Â° to 260Â° twist aligned nematic liquid crystal sandwiched between a first substrate provided with a reflector and a first electrode, and a second substrate provided with a plurality of second electrodes; a retardation film disposed on an outer side of the second substrate of the STN liquid crystal element; and a polarizing film disposed on an outer side of the retardation film; wherein where any one of said plurality of second electrodes overlaps with said first electrode defines a pixel; wherein a &Dgr;nd value indicating a birefringent tendency of the STN liquid crystal element is in a range from 0.7 &mgr;m to 0.8 &mgr;m; a retardation value R of the retardation film indicating a birefringent tendency thereof is in a range from 0.35 to 0.40 &mgr;m, and an intersection angle formed by a phase delay axis of the retardation film and an absorption axis or a transmission axis of the polarizing film is a range from 30Â° to 45Â°.
