Electronic device and electronic equipment provided with the electronic device

摘要

An electronic device having an intermediate layer which can transfer smoothly carriers between two layers adjacent to the intermediate layer and having improved properties, and electronic equipment having high reliability are provided. An electronic device includes a pair of electrodes and laminated layers provided between the electrodes. The laminated layers include a hole transport layer (first organic semiconductor layer), a light emitting layer (second organic semiconductor layer), and an intermediate layer provided between the first and second organic semiconductor layers so as to make contact with both of the hole transport layer and the light emitting layer. The intermediate layer is constituted of a compound represented by a general formula A1-B-A2. In this formula, each of the A1 and A2 is a group including at least one of a primary amino group, a secondary amino group, a tertiary amino group, a hydroxyl group, a carbonyl group and a carboxyl group, the A1 and A2 are the same or different, and optionally simultaneously exist, and the B is a group including a fluorene ring. Molecules of the compound are oriented in a state that each group A1 and each group A2 are positioned on the side of the hole transport layer and each group B is positioned on the side of the light emitting layer.
