Claim Text:
1. A stage circuit, comprising: a first supply circuit to supply a scan signal to a first output terminal, based on voltages received by a first input terminal, a second input terminal, and a fourth input terminal; and a second supply circuit to supply an emission control signal to a second output terminal, based on voltages received by the first input terminal, the second input terminal, the first output terminal, and a third input terminal, wherein the second supply circuit includes: a first transistor coupled between the first output terminal and a third node, the first transistor having a gate electrode coupled to the second input terminal; a second transistor coupled between the third input terminal and a fourth node, the second transistor having a gate electrode coupled to the third node; a third transistor coupled between the third input terminal and the second output terminal, the third transistor having a gate electrode coupled to the third node; and a fourth transistor coupled between the second output terminal and a second power source set to a gate-on voltage, the fourth transistor having a gate electrode coupled to the fourth node.
