Abstract
A display panel includes a substrate, pixels disposed on the substrate, and an insulating layer disposed on the substrate. Each of the pixels includes pixel driving circuits, pad groups and light emitting elements. The pad groups are electrically connected to the pixel driving circuits respectively. The light emitting elements are respectively bonded to the pad groups. The insulating layer includes a first edge portion. The first edge portion of the insulating layer are located outside the pad groups of the pixels.
