Abstract
A display panel includes an upper display substrate in which first to third pixel regions respectively configured to emit first to third light are defined, and a lower display substrate including first to third light-emitting elements respectively overlapping the first to third pixel regions. The first light-emitting element and the second light-emitting element each include one or more first stack parts and one or more first charge generation layers, each of the one or more first stack parts including a first emission layer configured to emit the second light. The third light-emitting element includes one or more second stack parts and one or more second charge generation layers, each of the one or more second stacking parts including a second emission layer configured to emit the third light. The first charge generation layer includes organic dopants, and the second charge generation layer includes inorganic dopants.
