摘要
An organoelectroluminescent element which can satisfy both a high external quantum efficiency and high power efficiency at the same time, which has on a substrate an anode, a first intermediate organic layer composed of at least one organic layer, a light-emitting layer, a second intermediate organic layer composed of at least one organic layer, and a cathode in this order, and in which light is extracted from the aforementioned anode side, wherein the aforementioned light-emitting layer contains a light-emitting material that is oriented in the horizontal direction with the substrate, the order parameter of the aforementioned light-emitting material in the aforementioned light-emitting layer is at least 0.7, and the relationship between the thickness T1 (nm) of the aforementioned first intermediate organic layer and the thickness T2 (nm) of the aforementioned second intermediate organic layer is such that 1.1
