Abstract
A display substrate and a touch-control display device are disclosed. The display substrate comprises pixel units arranged in an array on a base substrate, signal lines, and a grid-shaped cathode layer; a sub-pixel in the pixel unit comprises a pixel opening area; the cathode layer comprises first cathode patterns and a second cathode patterns, the first cathode patterns are arranged in an array, and adjacent first cathode patterns are coupled via at least one second cathode pattern; an orthographic projection of the first cathode pattern onto the base substrate covers each pixel opening area in a corresponding pixel unit; an orthographic projection of the second cathode pattern onto the base substrate at least partially overlaps with an orthographic projection of at least part of the signal lines onto the base substrate.
