Abstract
A stage in an emission control driver of a display device includes an input unit to control a voltage of a first node and a second node in response to a first input signal supplied from a first input terminal and a second input signal supplied from a second input terminal, respectively; a first controller to control a voltage of a third node and a fourth node in response to a third input signal supplied from a third input terminal and the voltage of the second node; a second controller to control the voltage of the fourth node in response to the voltage of the first node; and an output unit to supply a voltage of a first power supply or a second power supply to an output terminal in response to the voltage of the third node or the voltage of the fourth node. The first controller includes a first transistor and a second transistor connected between the first power supply and the third node; and a third transistor connected between the first node and the third node, the first transistor being turned on in response to the voltage of the second power supply.
