The invention provides a manufacturing method of a light emitting device, a light emitting device and a mixed light emitting device. The manufacturing method includes the following steps: step S1, setting a mask plate with a plurality of hollowed out parts on the substrate; step S2, using a solution method to make the ink pass through the hollowed out parts to be placed on the surface of the substrate; step S3, drying the ink on the surface of the substrate , forming a light-emitting layer or a functional layer. Since the manufacturing method is to arrange a mask plate with a plurality of hollow parts on the substrate, and then use a solution method to make the ink pass through the hollow parts on the surface of the substrate, and then dry the ink on the surface of the substrate to form a light-emitting layer or a functional layer, Therefore, the dispersion of the ink to other color regions is blocked by using the mask, effectively avoiding the problem of color mixing, and improving the color accuracy of the light-emitting device. |
