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 reflection-type liquid crystal display device comprises a liquid crystal cell, a polarizing film, a birefringent film, a scattering layer, and a light reflection means, in which a diffuse reflection factor “R” of the scattering layer is designed to be 7% or greater, but 110% or less when an incident angle of light is in the range of 25° or greater and 45° or smaller. Here the diffuse reflection factor “R” is defined by the formula of R=R1/R2×100 (where R1 is a reflection factor irradiated at an incident angle of 0°, and R2 is a reflection factor irradiated at an incident angle of 25°). This structure is able to provide a reflection-type LCD which is bright in White display, capable of producing a high contrast, and reducing blur of an image.
