Reflection type liquid crystal display device with high-brightness bright display and high contrast

A reflection type liquid crystal display device comprising a liquid crystal cell, the liquid crystal cell having first and second transparent substrates, a liquid crystal layer between the first and second transparent substrates, a first transparent electrode and a first alignment layer provided between the first transparent substrate and the liquid crystal layer, a second transparent electrode and a second alignment layer provided between the second transparent substrate and the liquid crystal layer, a first phase difference plate adjacent to the second transparent substrate, a second phase difference plate on the first phase difference plate, and a polarizer adjacent to the second phase difference plate,

• wherein the liquid crystal layer is twisted by 240 to 250 degrees in a thickness direction and the liquid crystal cell has a retardation (ΔndLC) of 600 nm to 700 nm;
• and
• wherein, viewing from a light incidence side:
• an alignment direction a of the second alignment layer, an alignment direction b of the first alignment layer, and a direction X bisects the alignment directions a and b,
• a retardation (ΔndRF1) for the first phase difference plate is 100 nm to 200 nm and a lagging axis β of the first phase difference plate forms an angle (φRF1) of 60 to 100 degrees in a counterclockwise direction with respect to the direction X;
• wherein a retardation (ΔndRF2) for the second phase difference plate is 300 nm to 500 nm and a lagging axis γ of the second phase difference plate forms an angle (φRF2) of 90 to 140 degrees in the counterclockwise direction with respect to the direction X;
• and
• wherein an angle (φpo1) formed by an absorption axis α of the polarizer with respect to the direction X is between 20 and 70 degrees or between 110 and 160 degrees in the counterclockwise direction.
