Reflective liquid crystal display device

A reflective liquid crystal display device comprising:

• a liquid crystal cell comprising a liquid crystal layer, having a thickness dLC, of liquid crystal, having a birefringence of .DELTA.nLC, sealed between a first substrate and a second substrate, the liquid crystal cell having a first substrate side and a second substrate side;
• a polarizer layer disposed on the first substrate side of said liquid crystal cell;
• two sheets of retardation layer disposed between said polarizer layer and said liquid crystal layer;
• at least one scattering layer disposed between said polarizer layer and said liquid crystal layer;
• and
• an optical reflector disposed on the second substrate side of the said liquid crystal layer;
• wherein a twisting angle of said liquid crystal is between 220.degree. and 260.degree., a multiple .DELTA.nLC.multidot.dLC of said birefringence .DELTA.nLC of said liquid crystal multiplied by said liquid crystal layer thickness dLC is between 700 nm and 1000 nm, and the liquid crystal display device satisfies formula 2 and one of set of formulae 3-5 or set of formulae 8-10:
• .vertline.Rfilm(2)-Rfilm(1).vertline..ltoreq.200 nm (2)
• 100.degree..ltoreq..o slashed.F1-.o slashed.LC.ltoreq.140.degree.(3)
