<p>PURPOSE: A compound having two or more 5-membered heterocycles is provided to improve photonic efficiency and lifetime, and stability of a device. CONSTITUTION: A compound having two or more 5-membered hetercycles is denoted by chemical formula 1. An organic electronic device contains one or more organic layers containing the compound. The compound forms an organic layer by a soluble process. The organic electronic device is an organic electroluminescent device comprising a first electrode, one or more organic layers, and a second electrode. The organic layer is a hole injection layer, a hole transport layer, a light emitting layer, electron transport layer, or electron injection layer. A terminal comprises a display having the organic electronic device and a controller driving the display device.</p> |
