Abstract: One aspect of the present disclosure provides a display device including: a display panel including a plurality of sub pixels; a reflective electrode disposed in each of the plurality of sub pixels; a first light-emitting element disposed on the reflective electrode; a first connection electrode disposed on the first light-emitting element and configured such that at least a part of the first connection electrode covers the first light-emitting element; and a second light-emitting element disposed on the first connection electrode and configured to overlap the first light-emitting element, in which the first light-emitting element has a larger size than the second light-emitting element. Therefore, the first light-emitting element has a relatively large size, such that the second light-emitting element may be more easily aligned and disposed on the first light-emitting element.

Abstract: A display device includes a display panel including a plurality of sub pixels. At least one of the sub pixels may include a light emitting diode configured to emit light, a light emitting circuit configured to drive the light emitting diode, and a sensing circuit including a photo sensing transistor configured to sense light emitted from the light emitting diode. Accordingly, the light intensity of the sub pixel may be sensed by the sensing circuit in real time to compensate for a luminance deviation between the plurality of sub pixels.
