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.
