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.

Abstract: A display device includes a level shifter and a gate driving circuit that can reduce differences in characteristics among gate signals to improve image quality by controlling a signal waveform of a first clock signal of the m number of clock signals different from a signal waveform of an m-th clock signal when m number of gate signals is output by using m number of clock signals.
