Abstract: The present application provides an array substrate, a method for fabricating the array substrate, and a display device. The method for fabricating the array substrate includes: forming a plurality of light-shielding electrode structures spaced apart from each other on a substrate; forming an insulating film on a side of the substrate close to the light-shielding electrode structures, the insulating film covering the plurality of light-shielding electrode structures and the substrate; and forming insulating barriers between adjacent light-shielding electrode structures by performing exposure from a side of the substrate away from the light-shielding electrode structures.

Abstract: The disclosure provides a display substrate and a manufacturing method thereof, a display panel and a display apparatus. The display substrate includes a substrate and an electroluminescent layer on the substrate. The display substrate further includes a first reflective electrode layer, a buffer layer and a second reflective electrode layer sequentially formed on a side of the electroluminescent layer distal to the substrate. The buffer layer is provided with a first hollow region, the second reflective electrode layer is provided with a second hollow region, an overlapping region between the first hollow region and the second hollow region is configured to transmit light emitted by the electroluminescent layer. The present disclosure can detect the light-emitting brightness of each sub-pixel in the organic electroluminescent layer in real time to improve light-emitting efficiency.
