摘要： The present disclosure provides an array substrate, a method for manufacturing the array substrate, a display panel and a display device. The array substrate includes: a substrate; a planarization layer on a side of the substrate; a pixel defining layer configured to define a pixel opening region and located on a side of the planarization layer away from the substrate; an anode in the pixel opening region and on a side of the planarization layer away from the substrate. The array substrate further includes an intermediate insulation layer between the planarization layer and the pixel defining layer. The intermediate insulation layer has a chemical polarity between a chemical polarity of the planarization layer and a chemical polarity of the pixel defining layer.

摘要： An array substrate, a preparing method thereof, a display panel and a display apparatus are disclosed. The array substrate includes: a base substrate (1); a driving circuit structure (2) on the base substrate (1); a planarization layer (3) and a plurality of electrode structures (4) successively located on a side, facing away from the base substrate (1), of the driving circuit structure (2); insulation structures (5) in gap areas between adjacent electrode structures (4); and pixel defining structures (6) on a side, facing away from the base substrate (1), of the insulation structures (5). The thickness of the insulation structures (5) is not smaller than the thickness of the electrode structures (4). An orthographic projection of the pixel defining structures (6) on the base substrate (1) at least completely covers the insulation structures (5).
