Abstract

Disclosed are a display substrate, a display device, and a manufacturing method. The display substrate includes: a base substrate; gate lines and data lines which define a plurality of sub-pixel regions; sub-pixel electrodes located in the plurality of sub-pixel regions on the base substrate; driving transistors disposed on the base substrate and electrically connected with the data lines, the gate lines and the sub-pixel electrodes; and a bar structure on a side of a layer where the sub-pixel electrodes are located away from the base substrate. The bar structure has an opening region for accommodating charged particles in each sub-pixel region, an orthographic projection of the bar structure at least partially covers orthographic projections of the gate lines and the data lines on the base substrate, and a ratio of an area of a sub-pixel electrode to an area of a sub-pixel region is greater than 70%.
