光提取膜、面发光体及光提取膜的制造方法;LIGHT EXTRACTION FILM, SURFACE LIGHT EMITTING BODY AND PRODUCTION METHOD OF LIGHT EXTRACTION FILM

摘要

本发明为一种光提取膜，且构成光提取膜的材料包含矩阵树脂（X）、离子液体（Y）及光扩散微粒子（Z）。本发明为一种包含所述光提取膜的面发光体。本发明为一种光提取膜的制造方法，用于制造积层于电致发光元件的基板上的光提取膜，包括：将包含活性能量线硬化性组成物、离子液体（Y）及光扩散微粒子（Z）的混合物供给至基材与具有凹凸结构的转印部的模具之间，并照射活性能量线。; a surface light emitting body containing the light extraction film; and a production method of a light extraction film laminated on a substituent of an EL element, including supplying a mixture containing an active energy ray-curing composition, an ion liquid (Y), and a light diffusing fine particle (Z) between a substituent and a mold containing a transfer portion having a concave-convex structure, and irradiating an active energy ray to the mixture.
