Patent ID: 8334647

Claim:
An organic EL device in which charges are injected into a luminescent layer of an organic thin film formed between a first electrode layer and a second electrode layer, thereby emitting a light, the organic EL device comprising: a charge injection layer formed between the luminescent layer and the second electrode layer; and a charge transporting layer formed between the luminescent layer and the charge injection layer, wherein the charge transporting layer consists of a matrix organic material, the charge injection layer consisting of a thin film in which a charge injectable metallic material and the same matrix organic material as the charge transporting layer are mixed, the charge injectable metallic material is lithium, and a weight ratio of the lithium in the charge injection layer is at least 2%, wherein the nearer the charge injection layer is to the charge transporting layer, the larger the proportion of the matrix organic material becomes, and wherein a metallic film formed by a sputtering method is disposed on a surface of the charge injection layer.
