Based on the same inventive concept, embodiments of the present disclosure further provide a display apparatus. As shown in FIG. 13, the display apparatus includes the display panel in the embodiments and has the beneficial effects of the display panel provided by the above embodiments of the present disclosure, which is not repeated here.

Specifically, the display apparatus provided by the embodiments of the present disclosure may further include a driving chip and a power supply. The driving chip provides a driving signal for the display panel, and the power supply provides electrical energy for the display panel.

By applying the embodiments of the present disclosure, the following beneficial effects may be at least achieved.

The display substrate, the display panel and the display apparatus provided by the embodiments of the present disclosure utilizes the first pixel defining structure to form the plurality of openings corresponding to the pixel columns, and utilizes the second pixel defining structure to divide the sub-pixels, and the pixel column openings corresponding to each of at least one color are communicated in the virtual pixel region, so that the ink (the solution containing the organic light-emitting layer material) forming the sub-pixels of the color can be circulated in the plurality of pixel column openings. Even if part of pixel column openings is not communicated, the ink in the part of pixel column openings may also be circulated in the part of pixel column openings. In this way, the uniformity of the thickness of the organic light-emitting layer is improved advantageously, thereby improving the display effect of the display apparatus.
