Abstract

A driving circuit and a display panel are provided. In a driving circuit structure, a clock signal line group includes a plurality of clock signal lines, the clock signal lines are arranged side by side, and there is a first pitch between two adjacent clock signal lines. A non-high frequency signal line is provided on two sides of the clock signal line group. A redundant clock signal line is disposed between the clock signal line group and the non-high frequency signal line, and a frequency and an amplitude of a signal received by the redundant clock signal line are the same as a frequency and an amplitude of a signal received by the clock signal line.
