Patent ID: 7161647

Claim:
A liquid crystal display device, comprising: a transflective liquid crystal panel, having: opposing first and second substrates, a liquid crystal layer disposed between the substrates and having liquid crystal molecules disposed in a twisted manner at an angle in the range of from 220 to 270 degrees, a first retardation film and a second retardation film sandwiching the liquid crystal layer from opposite sides of the liquid crystal layer, a first polarizer disposed at a side of the first retardation film that is opposite from a side of the first retardation film that faces the liquid crystal layer, a second polarizer disposed at a side of the second retardation film that is opposite from a side of the second retardation film that faces the liquid crystal layer a transflective layer that is disposed on an inner side of the second substrate and that reflects and transmits a portion of light incident upon the liquid crystal panel; and an illuminating device, wherein, in a pixel in a bright display of the liquid crystal panel, light emitted from the illuminating device and that is incident upon the first polarizer from the liquid crystal layer is elliptically polarized light, and the product of an optical anisotropy Δn and a thickness d of the liquid crystal layer, Δn·d, is in a range of from 820 nm to 950 nm, and the liquid crystal panel having a directional reflection function which causes light obliquely incident upon the liquid crystal panel to exit mainly in a direction perpendicular to the liquid crystal panel rather than in a specular reflection direction.
