    Abstract: The present invention discloses an array substrate and a manufacturing method thereof, and a display device, wherein the array substrate comprises a base substrate and an electroluminescent device disposed above the base substrate, the array substrate further comprises an additive layer between the base substrate and the electroluminescent device, with a plurality of protrusions being formed on a contact surface of the additive layer with the electroluminescent device, refractive index of the additive layer being less than or equal to that of the base substrate. Light generated by the electroluminescent device successively transmits through the additive layer and the base substrate so as to exit from the array substrate. In the technical solutions of the present invention, by arranging the additive layer between the base substrate and the electroluminescent device, the total amount of light “refracted” from the electroluminescent device into the base substrate can be effectively increased.
