The display substrate comprises a substrate, a first planar layer, and a BPS light-shielding layer. Wherein the BPS light-shielding layer is made of a composite material including polydopamine and graphene oxide, which can strengthen a binding force between the BPS light-shielding layer and the first planar layer and improve light-shielding effect of the BPS light-shielding layer. The manufacturing method of the display substrate is simple, and making liquid crystals uniformly filled, thereby improving display quality of panels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display panel, display substrate, and manufacturing method thereof","description":"The present disclosure provides a display panel, a display substrate, and a manufacturing method thereof.
