Abstract
A display panel includes: a display region; a peripheral region surrounding the display region; a base substrate; a first signal line, located on the base substrate, including an electrode structure located in the peripheral region, and an edge of the electrode structure away from the display region having a stepped shape; and a covering portion, covering the edge of the electrode structure away from the display region. The display panel adopts the covering portion to cover the edge of the electrode structure away from the display region, so as to protect the edge of the electrode structure, and to avoid the phenomenon of electrochemical corrosion of the edge of the electrode structure, the edge of the electrode structure away from the display region is designed to have a stepped shape, thereby prolonging a path for water vapor to enter the display region, and improving reliability of the display panel.
