Abstract
A red light-emitting element according to the present disclosure includes a pixel electrode, a red light-emitting layer, and a common electrode in the stated order. The red light-emitting layer includes the following: a first red function region including red nanoparticles and first red ligands; and a second red function region including red nanoparticles and second red ligands different from the first red ligands, and being adjacent to at least a part of the side surface of the first red function region. The volume resistivity of the second red function region is higher than the volume resistivity of the first red function region.
