Emission control line driver

An emission control line driver comprising a plurality of the stages, wherein each of the stages comprises:

• a first transistor connected between a first power source and a first output terminal, the first transistor being turned on or off in accordance with a voltage that applied to a first node;
• a second transistor connected between the first output terminal and a second power source, the second transistor being turned on or off in accordance with a voltage that applied to a second node;
• a third transistor connected between a first input terminal and the first node, the third transistor having a gate electrode connected to a second input terminal;
• a fourth transistor connected between the first power source and the second node, the fourth transistor having a gate electrode connected to the first node;
• a first controller connected to the first input terminal, the second input terminal, and a third input terminal, the first controller being configured to supply sampling signal to a second output terminal;
• and
• a second controller connected to the second input terminal and a fourth input terminal, the second controller being configured to control the voltage of the second node,
• wherein the first controller includes a fifth transistor connected between the first power source and the second output terminal, the fifth transistor having a gate electrode connected to the first output terminal via a protection unit.
