摘要： A liquid crystal display device of high display quality and superior sharpness is presented. Large bumps and small bumps made of synthetic resin material are formed on a glass substrate. The bottom diameters of the large bumps and small bumps are defined, for example, at 5 .mu.m and 3 .mu.m, respectively, and their interval is at least, for example, 2 .mu.m or more. Covering these bumps and filling the recesses among the bumps, a smoothing film is formed. On the smoothing film, a reflective metal film made of metal material such as aluminum is formed. This reflective a metal film is formed in plural rows in a longitudinal band form. On the glass substrate, the bumps, smoothing film, and reflective metal film are combined to compose a reflector. An orientation film is formed on the reflective metal film. By the electric field applied in the liquid crystal layer so as to be in the light shielding state when the retardation .DELTA.n.sub.1 d.sub.1 of the liquid crystal cell and the retardation .DELTA.n.sub.2 d.sub.2 of the substrate possessing optical phase compensating function satisfy .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline./.lambda.=0.25+m/2.+-.0.1 (m=0, 1, 2, . . . ), and in the light transmitting state when satisfying .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline..lambda.=m/2.+-.0.1 (m=0, 1, 2, . . . ), by crossing the director direction of the liquid crystal molecules of the liquid crystal cell and the slow direction of the substrate possessing optical phase compensating function almost orthogonally, the value of .vertline..DELTA.n.sub.1 d.sub.1 -.DELTA.n.sub.2 d.sub.2 .vertline./.lambda. is varied, and these two states are used to present a display. Further, the absorption axis or transmission axis of the polarizer is set at 30.degree. to 60.degree. to the director direction of the liquid crystal molecule of the liquid crystal cell to produce a reflective type liquid crystal display device with no parallax, high contrast, high sharpness, and high display quality.
