## Abstract

A display panel has a non-display area comprising a GOA wiring area is provided. The display panel includes GOA wirings disposed in the GOA wiring area, and an electrostatic shielding unit, disposed at least corresponding to the GOA wirings of part of the GOA wiring area. The electrostatic shielding unit is configured to prevent the GOA wirings from being damaged by static electricity.

## Claims

### Claim 1

A display panel having a non-display area, the non-display area comprising a GOA wiring area, the display panel comprising:
