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 (10) and a second light-emitting component (20). The first light-emitting component (10) comprises a first light-emitting layer (12) and a second light-emitting layer (14) and the second light-emitting component (20) comprises a third light-emitting layer (22). A combination of electrical connection of the first light-emitting component (10) and the second light-emitting component (14) is driven by AC current as a whole; the first light-emitting layer (12) and the second light-emitting layer (14) do not emit light at the same time; the third light-emitting layer (22) emits light at the same time either with the first light-emitting layer (12) or the second light-emitting layer (14). AC drive is adopted in the light-emitting structure and is easy to achieve adjustment of color and illumination intensity.
