Abstract:
An organic light-emitting device including: a substrate; an anode above the substrate; wiring above the substrate, spaced away from the anode in a direction parallel to a main surface of the substrate; a light-emitting layer above the anode, containing an organic light-emitting material; an intermediate layer on the light-emitting layer and the wiring, continuous over the light-emitting layer and the wiring and containing a fluoride of a first metal which is an alkali metal or an alkaline earth metal; an organic functional layer on the intermediate layer, continuous over the light-emitting layer and the wiring and made of an organic material having an electron transporting property or an electron injection property and doped with a second metal having a property of cleaving a bond between the first metal and fluorine in the fluoride; and a cathode on the organic functional layer, continuous over the light-emitting layer and the wiring.
