Gate driver and display device including the same

A display device comprising:

• a display panel on which a plurality of data lines, a plurality of gate lines crossing the data lines, a plurality of power lines configured to receive different constant voltages, and a plurality of sub-pixels are arranged;
• a data driver configured to supply a data voltage of pixel data to the data lines;
• a gate driver configured to supply gate signals to the gate lines;
• and
• a timing controller configured to control operation timings of the data driver and the gate driver,
• wherein the gate driver includes:
• a control signal output part configured to generate a control signal based on a control clock signal and a carry signal;
• a control signal selection part configured to transfer one of the control signal generated from the control signal output part or a low-potential voltage applied from a power line;
• a scan signal output part configured to generate a scan signal according to potentials of a first control node and a second control node that are charged or discharged according to a gate clock signal;
• and
• a scan signal selection part configured to selectively output the scan signal generated from the scan signal output part based on the control signal transferred from the control signal selection part.
