摘要： A light emitting device includes: a first electrode layer, a first dielectric layer, a first luminescent layer, a second luminescent layer, a second dielectric layer and a second electrode layer that are arranged sequentially in stack; a source electrode and a drain electrode, wherein the source electrode and the drain electrode are arranged in a same layer, and are both located between the first luminescent layer and the second luminescent layer; and an insulating layer provided in the same layer as the source electrode and the drain electrode, and located between the source electrode and the drain electrode. By controlling the two electrode layers separately, the two luminescent layers may separately and independently emit light. By providing different materials of the luminescent layers, the effect of light emission of multiple mixed colors or the effect of an increased light intensity may be realized.
