    Abstract: A light emitting display device includes a pixel circuit unit, a data distribution unit, a plurality of signal generating units, a unit light emitting diode, and a dummy opening. The pixel circuit unit is configured to generate an output current. The data distribution unit is configured to apply a data voltage to the pixel circuit unit through a data line. The plurality of signal generating units are respectively configured to apply a scan signal and a light emission control signal to the pixel circuit unit through a plurality of signal lines. The unit light emitting diode is configured to receive the output current of the pixel circuit unit and is attached to the pixel circuit unit. The dummy opening is formed in the region where the pixel circuit unit, the data distribution unit, and a plurality of signal generating units are not positioned.

    Abstract: A display includes a first sub-pixel that emits a first color light and a second sub-pixel that emits a second color light. The first sub-pixel includes a first anode pad electrode, a second anode pad electrode, a first cathode pad electrode, and a first light emitting element including a first sub-light emitting element disposed on the first anode pad electrode and the first cathode pad electrode, and a second sub-light emitting element disposed on the second anode pad electrode and the first cathode pad electrode. An area of the first cathode pad electrode is larger than an area of the first anode pad electrode or an area of the second anode pad electrode. The first sub-light emitting element and the second sub-light emitting element emit the first color light during different periods, and the first sub-light emitting element and the second sub-light emitting element emit a same color light.
