Abstract

A display device, a display substrate, and a manufacturing method of the display substrate. The display substrate includes a display region. The display region includes a transparent display region, and the transparent display region includes a first base and a plurality of first sub-pixels on the first base. Each of the first sub-pixels includes: a first electrode; a first pixel-defining layer disposed on the first electrode, the first-pixel defining layer being provided with an opening; a first light-emitting material layer disposed in the opening of the pixel-defining layer; and a second electrode disposed on the first light-emitting material layer. Further, a plurality of isolation pillars are provided on the first pixel-defining layer and configured to separate the second electrodes of adjacent first sub-pixels, the isolation pillar is T-shaped, and the isolation pillar is an integrally formed structure.
