Abstract: A display device can include a first sub light-emitting element, a second sub light-emitting element and a third sub light-emitting element. The first sub light-emitting element includes a 1-1 hole transport layer, a 1-2 hole transport layer disposed on the 1-1 hole transport layer, and a first organic light-emitting layer disposed on the 1-2 hole transport layer. The second sub light-emitting element includes a 2-1 hole transport layer, a 2-2 hole transport layer disposed on the 2-1 hole transport layer, and a second organic light-emitting layer disposed on the 2-2 hole transport layer. The third sub light-emitting element includes a 3-1 hole transport layer, a 3-2 hole transport layer disposed on the 3-1 hole transport layer, and a third organic light-emitting layer disposed on the 3-2 hole transport layer.
