Abstract: An optoelectronic device includes a first electrode, a second electrode that is spaced apart from the first electrode, an optoelectronic unit that is disposed between the first electrode and the second electrode, an insulating layer and a driving electrode. The optoelectronic unit includes an optoelectronic stack emitting or absorbing at least two wavelengths of light. The insulating layer is disposed on a lateral side of the optoelectronic stack that extends in a stacking direction of the optoelectronic stack. The driving electrode is disposed on the insulating layer at a location corresponding in position to the optoelectronic unit and is separated from the first and second electrodes.
