Abstract
A display panel, a light-emitting device, and a driving method thereof are provided. The light-emitting device includes a substrate, and a first electrode, a first light-emitting unit, a connecting layer, a second light-emitting unit, and a second electrode stacked up sequentially on the substrate. Polarities of the first electrode and the second electrode are opposite and reverse periodically in order that the first light-emitting unit and the second light-emitting unit illuminate alternately.
