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. 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 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.

摘要： A guest-host type liquid crystal display device not requiring the use of external polarizers, comprises: two guest-host type liquid crystal cells which are superimposed one upon the other and which are constructed in a manner that the liquid crystal molecules contained in the respective cells and located close to the boundary between the two cells are aligned in a direction parallel to the plane of the boundary, but that the direction of alignment of the molecules in one cell is perpendicular to that in the other cell when a voltage is applied, or alternatively when no voltage is applied. In case the perpendicular state is realized when a voltage is applied, the molecules are caused to be rearranged in a direction normal to the substrate by the removal of the applied voltage, whereas in case said state is realized when no voltage is applied, such rearrangement can be achieved by the application of a voltage. The liquid crystal material to be used in the cells is selected from nematic liquid crystal material having a positive dielectric anisotropy and a material having a negative dielectric anisotropy. The device may contain at least one additional cell which is superimposed upon the two cells.
