Abstract: A stretchable display panel including a first light-emitting module and a second light-emitting module. The first light-emitting module includes a first body, a plurality of first connectors extending from the first body in different directions and each having a predetermined elastic force, first satellite portions extending from the first body in directions different from the directions of the plurality of first connectors, a first adhesive member disposed on the first body, and a first light-emitting element disposed on the first satellite portion. The second light-emitting module includes a second body disposed on the first adhesive member, a plurality of second connectors extending from the second body in different directions and each having a predetermined elastic force, a second satellite portion extending from the second body in a direction different from the directions of the plurality of second connectors and not overlapping the first satellite portion.
