Abstract
A display panel includes a substrate, a first electrode, a light-emitting layer, and a second electrode. The first electrode is disposed on the substrate. The light-emitting layer is disposed on a surface of the first electrode away from the substrate. The light-emitting layer includes a light-emitting sublayer. A compressibility parameter of the light-emitting sublayer is greater than or equal to a first threshold, and the compressibility parameter is determined by an amount of deformation of the light-emitting sublayer under unit force.
