Abstract
An organic light emitting device according to an exemplary embodiment of the present invention includes: a substrate; a first signal line and a second signal line formed on the substrate and intersecting each other; a common voltage line formed on the substrate, and intersecting one of the first signal line and the second signal line; a switching thin film transistor connected to the first signal line and the second signal line; a driving thin film transistor connected to the switching thin film transistor; an insulating layer covering the first signal line, the second signal line, the switching thin film transistor, and the driving thin film transistor; a pixel electrode formed on the insulating layer, and electrically connected to the driving thin film transistor; an organic light emitting member formed on the pixel electrode and including an emission layer and a member layer; and a common electrode formed on the organic light emitting member, wherein the member layer is made of a plurality of layers including electrons or holes, and at least one layer of the member layer is disposed between the common voltage line and the common electrode to electrically connect between the comm…
