Abstract: A gate driver circuit and a display device including the same have a voltage difference between output lines of the gate driver circuit that is reduced. To this end, a first gate driver is disposed on one side of a display panel, while a second gate driver is disposed on side of the display panel opposite the one side. An odd-numbered output line of the first gate driver is connected to an even-numbered output line of the second gate driver, while an even-numbered output line of the first gate driver is connected to an odd-numbered output line of the second gate driver. Therefore, the voltage difference between the output lines of the gate driver circuit is minimized or reduced.

Abstract: Discussed are a display device and a gate driving panel circuit, and characteristic differences between scan signals can be reduced through differential design between scan bootstrapping capacitors included in scan output buffers for outputting scan signals. The gate driving panel circuit includes an output buffer block including two or more scan output buffers and a logic block. The corresponding scan bootstrapping capacitor included in a specific scan output buffer among the two or more scan output buffers has a different capacitance from the one or more corresponding scan bootstrapping capacitors included in one or more remaining scan output buffers, except for the specific scan output buffer among the two or more scan output buffers.
