    • Provided is a highly-reliable organic electroluminescence element in which loss of light due to surface plasmons generated on a metal surface is suppressed, the efficiency of light extraction to outside the element, and short circuits are unlikely to occur. The organic electroluminescence element includes a metal layer (1), on a surface of which a nanosize uneven structure is provided by a nanoparticle arrangement structure (6) in which nanoparticles (6a) are arranged in a planar fashion, and an organic layer (3) disposed on the uneven surface of the metal layer (1) and constituted by a plurality of layers including a light-emitting layer (31). Each interface between the plurality of layers of the organic layer (3) is flatter than the uneven surface of the metal layer (1).
    • 提供了一种高度可靠的有机电致发光元件,其中抑制了由于在金属表面产生的表面等离子体激发而导致的光损失,光提取到元件外部的效率以及短路不可能发生。 有机电致发光元件包括金属层(1),其纳米尺寸不均匀结构由纳米颗粒排列结构(6)提供,其中纳米颗粒(6a)以平面方式排列,并且有机层(3) )设置在金属层(1)的不平坦表面上并且由包括发光层(31)的多个层构成。 有机层(3)的多个层之间的每个界面比金属层(1)的不平坦表面平坦。
