The invention provides a transflective liquid crystal display device which provides both high-contrast, bright reflective and transmissive displays. The liquid crystal display device of the present invention can include a liquid crystal panel and a backlight. The liquid crystal panel includes a liquid crystal layer, which is disposed between an upper substrate and a lower substrate and whose liquid crystals are disposed in a twisted manner at an angle in the range of from 220 to 270 degrees, an upper retardation film and a lower retardation film, which are disposed above and below the liquid crystal layer so as to sandwich it; an upper polarizer 16 and a lower polarizer, which are disposed on the outer surfaces of their respective retardation films, and a sloping reflective layer. Light impinging upon the upper polarizer from the liquid crystal layer is elliptically polarized light. The product of an optical anisotropy .DELTA.n of the liquid crystal layer and thickness d of the liquid crystal layer, .DELTA.nd, lies in the range of from 820 nm to 950 nm. Light obliquely impinging upon the liquid crystal panel exits in a direction that is closer to a direction perpendicular to the liquid crystal panel than to a specular reflection direction.
