Abstract
A display panel includes a substrate, a drive layer, an isolation column, a light emitting device layer, and a through hole. The substrate has an opening area, a transition area surrounding the opening area, and a display area surrounding the transition area. The drive layer is arranged on a side of the substrate and covers the display area and the transition area. The portion of the drive layer located in the transition area includes a light reflective layer surrounding the opening area. The isolation column is arranged on a surface of the drive layer facing away from the substrate and is located in the transition area. The isolation column surrounds the opening area. A contour line of a projection of the isolation column on the substrate is located inside a contour line of a projection of the light reflective layer on the substrate.
