Abstract
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.
