The present invention provides a display device and its display substrate, and a manufacturing method of the display substrate. In the transparent display area, an opening is made by using a first pixel definition layer between adjacent first sub-pixels, and the opening includes a first sub-pixel from top to bottom. An opening and a second opening, the lateral dimension of the first opening is set to be smaller than the lateral dimension of the second opening, thereby isolating the second electrodes of adjacent first sub-pixels. The opening with a narrow top and a wide bottom has a good isolation effect on conductive materials, and the second electrode adjacent to the first sub-pixel will not be electrically connected; in addition, the isolation column used to isolate the second electrode in the prior art is omitted, which simplifies the transparency. The film layer structure of the display area can reduce the diffraction problem when imaging through the transparent display area.
