ORGANIC LIGHT-EMITTING DIODE

摘要

PROBLEM TO BE SOLVED: To provide an organic light-emitting diode that is driven by a lower voltage, and emits high-luminance and long-lived light. SOLUTION: The organic light-emitting diode comprises at least a hole transport layer 13; a light-emitting layer 14; and an electron transport layer 15 in which a fluoride of an alkali metal is doped in a pyridyl-group containing oxadiazole derivative between an anode 12 and a cathode 16 that are provided on a substrate 11.
