Abstract: The present application provides a backplane unit, a manufacturing method thereof, and a display device. The manufacturing method includes the following steps: forming a photoresist layer on an array substrate, wherein the array substrate comprises a substrate, an array layer, and a light-emitting element, the array layer is formed on the substrate, the light-emitting element is disposed on the array layer, and the photoresist layer is formed on a side of the array layer and the light-emitting element away from the substrate; performing exposure on at least a portion of the photoresist layer corresponding to the light-emitting element; forming a light-shielding layer on at least a side of the photoresist layer away from the array substrate, wherein the light-shielding layer exposes at least a side portion of the light-emitting element; and laterally stripping the photoresist layer on the light-emitting element with a stripping solution to obtain the backplane unit.
