Abstract
A display device includes an upper display substrate including a first pixel region for emitting a first light, a second pixel region for emitting a second light different from the first light, and a third pixel region for emitting a third light different from the first light and the second light; and a lower display substrate including a first light-emitting element overlapping the first pixel region, a second light-emitting element overlapping the second pixel region, and a third light-emitting element overlapping the third pixel region. The second light-emitting element includes one or more first stacks for emitting the second light, the third light-emitting element includes one or more second stacks for emitting the third light, and a concentration of a conductive material included in the one or more first stacks is higher than a concentration of a conductive material included in the one or more second stacks.
