Abstract
The present application discloses a display panel, and a light-emitting functional layer of the display panel. The light-emitting functional layer includes a first light-emitting layer and a second light-emitting layer. The first light-emitting layer includes a first light-emitting sublayer. The second light-emitting layer includes a second light-emitting sublayer. The first light-emitting sublayer has a first film compactness parameter, and the first film compactness parameter is greater than or equal to a first threshold. The second light-emitting sublayer has a second film compactness parameter, and the second film compactness parameter is greater than or equal to a second threshold. The first film compactness parameter and the second film compactness parameter are determined by an amount of change of the film under a unit force condition.
