Abstract
A display panel has a first non-display area between an opening area and a display area. The display area surrounds the first non-display area. The opening area penetrates the display panel. The display panel includes a substrate, a first functional layer, and a light-emitting functional layer. The first functional layer has a protruding portion at a warped position and has a first opening penetrating the first functional layer at the warped position. The first opening extends into the protruding portion to form a cavity having bottom and side surfaces. An included angle θ formed between the bottom surface and at least a part of the side surface satisfies 0<θ≤90°. A light-emitting functional layer located at a side of first functional layer away from substrate includes a common layer in first non-displaying and display areas and is split at protruding portion.
