Abstract:
1. A method for forming an organic light emitting device, the method comprising: forming a driving transistor including a gate electrode overlying a substrate, a semiconductor layer overlying the gate electrode and separated therefrom by a gate insulating layer, a source electrode and a drain electrode overlying the semiconductor layer and defining a channel region in the semiconductor layer; forming an insulating layer including at least one passivation layer on the driving transistor and having a contact hole; forming a light emitting diode overlying the driving transistor, the diode including, a first electrode electrically coupled to the drain electrode through the contact hole and overlying the driving transistor, an organic light emitting layer overlying the first electrode, and a second electrode overlying the organic light emitting layer; and forming an auxiliary electrode between the first electrode and the channel region and electrically coupled to a ground line and to the source electrode, wherein the auxiliary electrode completely covers the channel region of the semiconductor layer, the channel region being a portion of the semiconductor layer corresponding to a position between the source electrode and the drain electrode.
