Abstract
The present disclosure provides a light emitting device and a method for manufacturing the same, and a display device. The light emitting device includes a plurality of light emitting units including a red light emitting unit, a green light emitting unit, and a blue light emitting unit, each light emitting unit including a micro-cavity structure. The light emitting device includes an anode structure, a cathode and a functional layer therebetween. The functional layer includes a light emitting layer including a red light emitting layer at least partially located in the red light emitting unit, an orthographic projection of the red light emitting layer on the backplane not overlapping with that of the blue light emitting unit on the backplane; a green light emitting layer at least partially located in the green light emitting unit; and a blue light emitting layer at least partially located in the blue light emitting unit.
