GOA circuit and display panel

The invention relates to a GOA circuit and a display panel, the GOA circuit comprises a plurality of cascaded GOA units, if the nth-stage GOA unit is the previous two-stage GOA unit, a pull-up and pull-down control module is connected with a GSP signal, an (m-2) th-stage clock signal line and a first node, otherwise, the pull-up and pull-down control module is connected with the signal output end of the (n-2) th-stage GOA unit, the (m-2) th-stage clock signal line and the first node; the pull-up and pull-down module is respectively connected with the mth-level clock signal line, the first node and the second node; the capacitor module is connected with the first node and the second node. The noise elimination module is respectively connected with an mth-level clock signal line, a first node, a second node and a third node, and the third node is connected with a first low-level signal; and if the nth GOA unit is the previous three-stage GOA unit, the first clearing module is respectively connected with a VSS s
