摘要： A reflective liquid crystal display device comprising a polarizer, a retardation film, a front scattering film layer, and a liquid crystal cell having a mirror reflector, in which the front scattering film layer includes at least one film of which scattering angle range is asymmetrical to the normal direction of film. A plural front scattering films of which scattering angle range is asymmetrical to the film normal are laminated so that the projection direction onto the film surface in the central angle direction of the scattering angle range may be different. At least one of the scattering films for composing the scattering film layer is a front scattering film for scattering more strongly the transmission light from the second incident angle region not containing the film normal direction than the transmission light from the first incident angle region containing the film normal direction.

摘要： A reflector electrode is provided with hills and valleys thereon, and the reflector electrode is formed on an inside face of a transparent substrate having a transparent electrode and an opposite substrate. Light-scattering-liquid-crystal is provided with forward-scattering component and back-scattering component, so that scattering of reflected light from the reflector electrode is increased when the light-scattering-liquid-crystal is transparent. As a result, contrast is less dependent on a viewing angle, and a brighter quality display with higher color purity can be obtained.

摘要： An electrode width of intermediate connection wiring which connects terminal electrode and common electrode is made narrower than an electrode width of terminal electrode at forming an electrode pattern on one of substrates configuring a liquid crystal display device. This enables the prevention of detrimental effect of cutting and polishing the periphery of a liquid crystal cell onto the terminal electrode. A laser irradiation process required for removing the common electrode is eliminated, and thus manufacturing cost may be reduced.
