Abstract: A driver includes a stage that includes a first controller, a second controller, and a first output unit. The first controller controls a voltage level of a first node. The second controller controls voltage levels of a second node and a third node to be equal to the voltage level of a first node or an opposite voltage level of the voltage level of the first node, and controls a voltage level of a fifth node to be equal to the opposite voltage level of the voltage level of the first node. The first output unit may output a gate control signal, which has a first voltage when the second node and the third node is in an on-voltage level state, and has a second voltage when the fifth node is in an on-voltage level state.
