Display panel and display apparatus

A display apparatus, comprising a driving chip and a display panel, wherein the display panel comprises a substrate;

• the substrate has a display region and a border region surrounding the display region;
• the border region comprises a first power voltage line and a first planarization layer sequentially stacked on a side of the substrate;
• the border region has a first dam region surrounding the display region and a second dam region surrounding the first dam region;
• an orthographic projection of the first power voltage line on the substrate is within the first dam region;
• at least a part of an orthographic projection of the first planarization layer on the substrate is within the first dam region and the second dam region, and a part of the first planarization layer within the first dam region at least covers a side surface of the first power voltage line;
• and
• the first planarization layer has a first groove and a second groove, the first groove is between the first dam region and the display region, and the second groove is between the first dam region and the second dam region.
