Abstract
A display panel includes a display area, and the display area includes a first display area and a second display area; the first display area and the second display area each include light-emitting areas, and the second display area further includes light transmissive areas. The manufacturing method includes forming, on a side of a substrate, a light-to-heat conversion layer covering at least a second display area; forming, on a side of the light-to-heat conversion layer facing away from the substrate, a light-emitting functional layer and a second electrode layer each covering the display area, where portions of the second electrode layer which are located in at least adjacent two light-emitting areas are connected; and removing, in at least part of the plurality of light transmissive areas, the light-to-heat conversion layer and all film layers located on a side of the light-to-heat conversion layer facing away from the substrate.
