Abstract
The embodiments of the present disclosure disclose an electroluminescent device, a display device and a manufacturing method thereof. The electroluminescent device comprises: a substrate; a micro light emitting diode unit, configured to emit light of a first color in a first direction; and an organic light emitting diode unit, configured to emit light of a second color in the first direction, wherein the micro light emitting diode unit and the organic light emitting diode unit are disposed on the substrate in a stack, such that light of the first color and light of the second color are mixed to generate mixed light, and the first direction is a direction towards the substrate or a direction away from the substrate.
