Abstract
A display panel has a display region and a peripheral region. The display panel includes a substrate, a first metal layer disposed on the substrate, a planarization layer disposed on a side of the first metal layer away from the substrate, and a retaining wall structure located in the peripheral region and surrounding the display region. The first metal layer includes a signal line pattern located in the peripheral region. The planarization layer includes an opening in the peripheral region. At least a portion of the retaining wall structure is located in the opening. The signal line pattern is provided with at least one through hole, an orthogonal projection of the at least one through hole on the substrate is located within an orthogonal projection of the opening on the substrate, and is at least located on a side of an orthogonal projection of the retaining wall structure on the substrate.
