    • A light emitting device 10 has a supporting substrate 12; a first electrode 14 disposed on the supporting substrate; an electroluminescent layer disposed on the first electrode and including at least a light emitting layer 16; a second electrode 18 disposed opposite to the first electrode, with the electroluminescent layer being interposed therebetween; a resin layer 20 disposed on the second electrode directly or with an intermediate layer interposed therebetween, or on a surface of the supporting substrate at the opposite side of a surface where the first electrode is disposed; and light transmitting particles 22 scattered in the resin layer, and at least a portion of the light transmitting particles are scattered in the resin layer such that a part of each of the scattered particles is embedded in a surface of the resin layer at the side at which light is extracted from the light emitting layer.
    • 发光装置10具有支撑基板12; 设置在支撑基板上的第一电极14; 设置在所述第一电极上并且至少包括发光层16的电致发光层; 与第一电极相对设置的第二电极18,其间夹有电致发光层; 直接设置在第二电极上的树脂层20或者介于其间的中间层,或者在设置有第一电极的表面的相反侧的支撑基板的表面上; 以及散布在树脂层中的透光性粒子22,至少一部分透光性粒子散布在树脂层中,使得每个散射粒子的一部分嵌入树脂层的侧面的表面 从发光层提取出光。
