Abstract

Provided are an electronic device and a fabrication method thereof. The electronic device according to the concept of the present invention includes auxiliary interconnections disposed on a substrate, a light extraction layer that is provided on the substrate and fills between the auxiliary interconnection, and a first electrode provided on the auxiliary interconnections and the light extraction layer, wherein the light extraction layer may have a first surface facing the substrate and a second surface opposite to the first surface, the first surface may have protrusions, and the auxiliary interconnections may include a material having a lower resistance than the first electrode. Since electrical properties of the electronic device are improved, uniform light emission characteristics may be realized.
