| 发明名称 | Light-diffusing element and polarizing plate provided therewith | ||
| 摘要 | There is provided a light diffusing element of a thin film, which has high light diffusibility and a small depolarization factor. A light diffusing element according to an embodiment of the present invention includes: a first region having a first refractive index; a refractive index modulation region having a substantially spherical shell shape, which surrounds the first region; and a second region having a second refractive index, which is positioned on a side of the refractive index modulation region opposite to the first region. The light diffusing element has a haze of 90% to 99.9% and a depolarization factor of 0.2% or less. | ||
