An optical diffusing plate that gives a anisotropic scattering of a linearly polarized light and has an excellent diffusion property in a scattering direction, and that is suitable for improving visibility, brightness of a liquid crystal display, comprising a birefringent film and a minute domain with a birefringent characteristic different from the birefringent film in a dispersed state in the birefringent film, the birefringent film comprises a birefringent stretched film, and the minute domain comprises a positive uniaxial liquid crystal polymer, wherein a length of the minute domain in a direction of stretching axis is longer than a length in a direction orthogonal to the stretching axis, and the liquid crystal polymer is aligned perpendicularly to a stretching axis of the birefringent stretched film. |
