The present invention addresses the problem of providing an isomer-mixture metal complex composition that includes a plurality of atropisomers which are closely akin to each other in physical property and energy level and of providing an organic EL element using the isomer-mixture metal complex composition as a material for the organic EL element, the EL element having improved stability over time of the organometallic complex film, including a luminescent layer reduced in resistivity change, and giving a luminescent spectrum reduced in change in half-value width. Also provided are an illuminator and a display device which are obtained using the organic EL element. This isomer-mixture metal complex composition is a metal complex composition which is a mixture of isomers each comprising a metal atom and a plurality of ligands, and is characterized by containing a plurality of atropisomers because at least one of the ligands has an aromatic ring as a substituent and the free rotation of the axis of the bonding between the aromatic ring and the ligand is inhibited by the formation of a complex of the metal atom with other ligand(s).
本发明要解决的问题是提供一种异构体混合物金属络合物组合物,该组合物包括多种在物理性质和能级上彼此非常接近的异构体,并提供一种使用该异构体混合物金属络合物组合物作为有机EL元件材料的有机EL元件,该EL元件在有机金属络合物薄膜的长期稳定性方面有所改善,包括电阻率变化减小的发光层,以及半值宽度变化减小的发光光谱。此外,还提供了使用该有机 EL 元件获得的照明器和显示装置。这种异构体混合物金属络合物组合物是一种金属络合物组合物,它是一种异构体的混合物,每个异构体包括一个金属原子和多个配体,其特征是含有多个异构体,因为配体中至少有一个具有芳香环作为取代基,并且芳香环和配体之间键合轴的自由旋转受到金属原子与其他配体形成的络合物的抑制。
