Abstract
A pixel circuit is disclosed that includes an organic light-emitting diode, a driving transistor connected in series with the organic light-emitting diode and having a gate connected to a first node and a drain connected to a second node, a dual-gate transistor coupled between the first node and the second node, and a leakage current suppression structure for suppressing a change in a driving current of the organic light-emitting diode caused by a leakage current flowing through the dual-gate transistor. A display device having the pixel circuit is also disclosed.
