Abstract
A stage circuit is capable of concurrently or progressively supplying scan signals. The stage circuit includes a progressive driver including a first transistor and a second transistor, and a concurrent driver including an 11th transistor and a 12th transistor. When the first transistor, the second transistor, the 11th transistor, and the 12th transistor are turned off, lower voltages than voltages applied to source electrodes are applied to gate electrodes such that the transistors can be stably turned off.
