Abstract
A display panel including a substrate, a metal structure at side of substrate, and first insulating layer, the metal structure and the first insulating layer located on a non-display region, the first insulating layer has hollow region, the hollow region extends through the first insulating layer in direction perpendicular to plane of substrate, where the metal structure includes first portion and second portion that are connected to each other. the first portion overlaps a hollow region and the second portion overlaps first insulating layer. The maximum distance between a part of a surface of a side of first portion away from substrate and substrate is a first distance, the maximum distance between a surface of a side of second portion away from the substrate and the substrate is a second distance, and the first distance is greater than the second distance.
