Abstract: A display substrate is described that comprises: a display area, a retaining wall surrounding the display area, and a thin film encapsulation layer comprising a first inorganic barrier layer, an organic barrier layer, and a second inorganic barrier layer. The display area has a corner portion being a portion of the display area surrounded by the retaining wall. Convex dams are provided at a position on the substrate corresponding to the corner portion. A portion of the first inorganic barrier layer corresponding to the corner portion covers the convex dams, and a portion of the first inorganic barrier layer between the two adjacent convex dams forms a diversion trench. The organic barrier layer comprises cured organic material, and the organic material is provided on the portion of the first inorganic barrier layer at the corner portion under a capillary action of the diversion trench before curing.
