Abstract

Disclosed is a method of manufacturing an organic light emitting device, an organic light emitting device manufactured by using the method, and an electronic device including the organic light emitting device. The method includes (a) forming an insulating layer on a lower electrode, (b) etching the insulating layer to form an opening ranging from an upper surface of the insulating layer to the lower electrode so that an overhang structure having a lowermost circumference that is larger than an uppermost circumference is formed, (c) forming a conductive layer on an upper surface of the lower electrode in the opening and a surface of the insulating layer other than the overhang structure, (d) forming an organic material layer on the conductive layer formed on the upper surface of the lower electrode in the opening, and (e) forming an upper electrode on an upper surface of the conductive layer disposed on the upper surface of the insulating layer and an upper surface of the organic material layer.

Description

technical field [0001] The present invention relates to a method for preparing an organic light-emitting device, the organic light-emitting device prepared by the method and an electronic device including the organic light-emitting device, the organic light-emitting device has the function of preventing leakage current along the organic light-emitting device including a conductive layer An overhang structure that flows in the direction of the surface of the conductive layer. [0002] This application claims priority from Korean Patent Application No. 10-2006-0069978 and No. 10-2006-0069979, each filed with KIPO on July 25, 2006, the disclosures of which are incorporated by reference in their entirety way incorporated into this article. Background technique [0003] Organic light-emitting devices using organic light-emitting devices have been applied to various types of light-emitting devices due to their advantages of high brightness at low voltage, and they have the advant...
