Abstract
A display device includes a substrate, a first light emitting element, and a second light emitting element. The substrate includes at least one pixel area. The first light emitting element and the second emitting element are disposed in the pixel area. The first light emitting element emits light of a first color and has a first luminous efficiency-injection current density function. The second light emitting element emits light of a second color and has a second luminous efficiency-injection current density function, intersected with the first luminous efficiency-injection current density function to define a critical transform current density. The light of the first color and the light of the second color have a same color system.
