摘要：
A light-emitting element has a cathode, an anode, a light-emitting portion interposed between the cathode and the anode and having a light-emitting layer that emits light on energization between the cathode and the anode, and a hole-injection layer interposed between and in direct contact with the anode and the light-emitting layer and having a capability of receiving holes, and the hole-injection layer is mainly composed of a benzidine derivative.
