Abstract: A gate driving circuit and a display panel. The gate driving circuit includes a plurality of cascaded gate driving units, wherein a Nth stage gate driving unit includes a pull-up control module and a node signal control module. By an adjustment of the signals connected to a first input terminal, a second input terminal, a first control terminal, and a second control terminal of the node signal control module, an original driving time sequence can be realized without using a clock signal, which reduces a space occupied by a frame.
