Abstract
This invention discloses an ESD protection circuit. The ESD protection circuit is arranged on a display panel. It comprises a first conductive via layer electrically connected with a first signal line for outputting signal and a second signal line for inputting signal, and a thin film transistor. A gate of the thin film transistor is electrically connected with a drain, and the second signal line is electrically connected with the gate and/or the drain of the thin film transistor, and the first signal line is electrically connected with a source of the thin film transistor. This invention also discloses a display panel and a display device. In the present invention, the disconnection of the signal line due to electrostatic breakdown is solved.
