Abstract
Embodiments of the present disclosure provide a display substrate and a display panel. The display substrate has a light-transmissive region and a light-shielding region, and the light-shielding region includes a main support region and a secondary support region. The display substrate includes a substrate, an alignment layer on the substrate, and a convex structure on the alignment layer. The convex structure is on a side of the alignment layer distal to the substrate and at least in the main support region, and a distance from a surface of the convex structure distal to the substrate to the substrate is greater than a distance from a surface of the alignment layer distal to the substrate to the substrate.
