Gate driver, display device including the gate driver and electronic device including the display device

A display device comprising:

• a display panel including a pixel;
• a gate driver which outputs a gate signal to the pixel;
• a data driver which outputs a data voltage to the pixel;
• and
• a driving controller which controls the gate driver and the data driver,
• wherein the gate driver includes:
• an input circuit which transmits an input signal to a first control node based on a clock signal;
• a control circuit which transmits a first power supply voltage to a third control node based on the input signal, and transmits the first power supply voltage to a second control node based on the first power supply voltage and a voltage of the third control node;
• a first output circuit which outputs the gate signal having a second power supply voltage or a third power supply voltage based on a voltage of the first control node and a voltage of the second control node;
• and
• a second output circuit which outputs a carry signal having the third power supply voltage or the first power supply voltage based on the voltage of the second control node, wherein the carry signal has a phase opposite to a phase of the gate signal.
