CPC classification number: G02F1/133606 , G02B5/0242 , G02F2001/133607 , G02F2201/44 , H01L51/0096 , H01L51/5234 , H01L51/5268 , H01L51/5271
Abstract: An EL element including an EL light-emitting structure including a light-emitting layer on a transparent electrode, and a counter electrode on the light-emitting layer, a translucent substrate, and a light scattering layer between the EL light-emitting structure and the translucent substrate, the light scattering layer having a first surface on a transparent electrode side and a second surface on a side of the translucent substrate. The light scattering layer includes light scattering particles which includes particles that form agglomerates in a portion of the first surface such that the portion of the first surface has a concavo-convex shape. The light scattering particles further include particles positioned in order along the second surface such that the second surface is smoother than the portion of the first surface having the concavo-convex shape.
Abstract translation: 包括在透明电极上包括发光层的EL发光结构和发光层上的对电极，透光性基板和在所述EL发光结构和所述发光层之间的光散射层的EL元件 所述光散射层具有透明电极侧的第一面和所述透光性基板一侧的第二面。 光散射层包括光散射颗粒，其包括在第一表面的一部分中形成附聚物的颗粒，使得第一表面的部分具有凹凸形状。 光散射颗粒还包括沿着第二表面依次定位的颗粒，使得第二表面比具有凹凸形状的第一表面的部分更光滑。
