Reflection liquid crystal display element

A reflective liquid crystal display device comprising;

• a) a liquid crystal cell formed by injecting a nematic liquid crystal in between a first and a second substrates;
• b) a polarizing film disposed on said first substrate of said liquid crystal cell;
• c) two retardation films disposed in between said polarizing film and said liquid crystal cell;
• and
• d) a light reflecting means disposed on said second substrate,
• wherein a twist angle of said nematic liquid crystal ΩLC is 45°˜90°, a product ΔnLC·dLC is 0.20 μm˜0.30 μm where ΔnLC and d LC are respectively birefringence of said nematic liquid crystal and thickness of a liquid crystal layer, a retardation value of said retardation film on said polarizing film side RF1 is 0.13μm˜0.18 μm, a retardation value of said retardation film on said liquid crystal cell side RF2 is 0.13 μm˜0.18 μm, and the Z coefficient, QZ of each of said two retardation film is 0.3˜1.0,
• wherein when a bisector of a larger of the angle formed by an orientation direction of liquid crystal molecules closest to said first substrate and an orientation direction of liquid crystal molecules closest to said second substrate is set as a reference line, and when a direction, in which said nematic liquid crystal is twisted from said first substrate to said second substrate, viewed from the side of said first substrate, is defined positive, ØP is −15°˜105°, ØP−ØF1, −105°˜−115°, and ØP−ØF2, −165°˜−175°,
• where ØP is an angle formed by the reference line and a direction of an absorption axis of said polarizing film, ØF1 is an angle formed by the reference line and a direction of a slow axis of said retardation film on said polarizing film side, and ØF2 is an angle formed by the reference line and a direction of a slow axis of said retardation film on said liquid crystal cell side, and the aforementioned QZ is a coefficient defined as
• QZ=(nx−nz)/(nx−ny),
• where nx, ny and nz are refractive index of each retardation film in directions of each axis in spatial coordinates x, y and z in which the z axis is a direction normal to surfaces of the retardation films, and nx is a refractive index in a direction of the slow axis and ny an fast axis of the retardation film.
