Optical diffusing plate, optical element and liquid crystal display |
摘要 |
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 minute domain comprising a side chain type liquid crystal polymer comprising a monomer unit (a) containing a liquid crystalline fragment side chain and a monomer unit (b) containing a non-liquid crystalline fragment side chain, and a refractive index difference (DELTAn1) between the birefringent film and the minute domain in a direction orthogonal to a direction of axis that gives a maximum transmittance of linearly polarized light being 0.03 or more, and a refractive index difference (DELTAn2) in a direction of axis that gives a maximum transmittance being 80% or less of the DELTAn1.
