Abstract
The present invention relates to an organic light-emitting device and to a method of manufacturing same. The organic light-emitting device comprises: a first electrode comprising two or more conductive units, and conductive connection parts respectively connected to the two or more conductive units; a second electrode disposed opposed to the first electrode; an organic layer disposed between the first electrode and the second electrode and consisting of one or more layer; an auxiliary electrode electrically connected to the respective conductive connection parts; and an insulating layer disposed between the conductive connection part and the auxiliary electrode so as to insulate at least a portion of the conductive connection part from the auxiliary electrode. Here, the conductive connection part comprises a short-circuit preventing region of which the length in the current-flowing direction is longer than the width in the direction perpendicular thereto.
Description
Technical field [0001] The invention relates to an organic light emitting device and a manufacturing method thereof. [0002] The present invention claims the priority of Korean Patent Application No. 10-2013-0055997 filed with the Korean Intellectual Property Office on May 16, 2013, and the entire content of the disclosure is incorporated into this specification by reference. Background technique [0003] Organic luminescence refers to the phenomenon of using organic materials to convert electrical energy into light energy. That is, when an appropriate organic layer is placed between a negative electrode (anode) and a positive electrode (cathode), and then a voltage is applied between the two electrodes, holes are injected into the organic layer from the negative electrode, and Electrons are injected into the organic layer from the positive electrode. When the injected holes and electrons meet, excitons are generated, and when the excitons fall to a bottom state, light is genera...
