Abstract
A display device includes a first substrate, a first active element layer, first to third light-emitting elements, a first pixel defining layer, and fourth to sixth light-emitting elements. The first active element layer is disposed on the first substrate. The first, second and third light-emitting elements are electrically connected with the first active element layer. The first, second and third light-emitting elements have first, second and third light-emitting layers respectively. The first pixel defining layer is disposed on the first active element layer and has first, second and third openings. The first, second and third light-emitting layers are disposed in the first, second and third openings respectively. The fourth, fifth and sixth light-emitting elements are disposed on the first pixel defining layer. A vertical distance between the first light-emitting element and the fourth light-emitting element is greater than 0 micrometers and less than or equal to 5 micrometers.
