Abstract
A display panel includes a pixel defining layer, light-emitting unit, first support post, and touch layer. The light-emitting unit includes first electrode, light-emitting layer, and second electrode. The first support post is located between the pixel defining layer and the first electrode in direction perpendicular to display panel, and is located in non-aperture region of the pixel defining layer. The first electrode covers the light-emitting layer and the first support post. The touch layer is located at a side of the first electrode away from the pixel defining layer, and includes hollow portion, first portion and second portion that are mutually connected. In direction perpendicular to the display panel, both first portion and hollow portion overlap first support post, second portion does not overlap first support post. Overlapping portion of first portion and first supporting post has smaller area than first supporting post. A display device is also provided.
