Abstract

A display device is provided. The display device includes a first substrate, a first element layer, a first light-emitting element layer, a second substrate, a second element layer, and a second light-emitting element layer. The first element layer is disposed on the first substrate and includes a first active element. The first light-emitting element layer is disposed on the first element layer and includes a first light-emitting element, the first light-emitting element is electrically connected to the first active element and includes a first light-emitting layer. The second substrate is disposed on the first light-emitting element. The second element layer is disposed on the second substrate and includes a second active element. The second light-emitting element layer is disposed on the second element layer and includes a second light-emitting element, the second light-emitting element is electrically connected to the second active element and includes a second light-emitting layer. The first light-emitting layer and the second light-emitting layer do not overlap with each other in the normal direction of the first substrate.
