Light diffusing element, polarizing plate with light diffusing element, liquid crystal display apparatus using both, and manufacturing method for light diffusing element
摘要：
A light diffusing element of the present invention includes: a matrix containing a resin component and an ultrafine particle component; and light diffusing fine particles dispersed in the matrix, wherein refractive indices of the resin component, the ultrafine particle component, and the light diffusing fine particles satisfy the below-indicated expression (1); and the light diffusing element comprises a concentration adjusted area, which is formed in an outer portion of a vicinity of a surface of each of the light diffusing fine particles, and in which a weight concentration of the resin component decreases and a weight concentration of the ultrafine particle component increases with increasing distance from the light diffusing fine particles: |np−nA|
摘要（中）：

本发明的光漫射元件包括：含有树脂成分和超微粒成分的基质; 以及散射在基体中的微细散射光，其中树脂成分，超微粒成分和光扩散性微粒的折射率满足下述式（1）。 并且所述光散射元件包括浓缩调整区域，其形成在每个所述光散射细颗粒的表面附近的外部，并且所述树脂组分的重量浓度降低，并且所述重量浓度 超细颗粒成分随着距离光扩散微粒的距离的增加而增加：| np-nA | <| np-nB | （1）其中，nA表示基体的树脂成分的折射率，nB表示基质的超细粒子成分的折射率，np表示光扩散性微粒的折射率。
