Abstract

A light-emitting structure, a display device and a light source device are disclosed; the light-emitting structure comprises a first light-emitting component () and a second light-emitting component (). The first light-emitting component () comprises a first light-emitting layer () and a second light-emitting layer () and the second light-emitting component () comprises a third light-emitting layer (). A combination of electrical connection of the first light-emitting component () and the second light-emitting component () is driven by AC current as a whole; the first light-emitting layer () and the second light-emitting layer () do not emit light at the same time; the third light-emitting layer () emits light at the same time either with the first light-emitting layer () or the second light-emitting layer (). AC drive is adopted in the light-emitting structure and is easy to achieve adjustment of color and illumination intensity.
