Abstract:
An organic electroluminescence device includes, in order, a first electrode, a hole transport layer, an organic light-emitting layer, an electron transport layer, and a second electrode. The hole transport layer is configured by a coated film. The organic light-emitting layer is configured by a coated film. The organic light-emitting layer has a hole current that is larger than an electron current.
