ORGANIC LIGHT EMITTING DEVICE

摘要

PURPOSE: An organic light emitting device is provided to improve the photonic efficiency of the organic light emitting device by including an AI group reflective film having a first element and Ni. CONSTITUTION: In an organic light emitting device, a first electrode(5) is formed on a substrate(1). The first electrode comprises an Al group reflective film(5a) and a transparent conductive film(5b) including a first element and Ni. A first layer(6) including the cyano group - containing compound is formed on the first electrode. An organic layer(7) is formed on the first layer. A second electrode(9) is formed on the organic layer.
