    Abstract: A light emitting substrate (100) and a display device are provided. The light emitting substrate (100) includes a light emitting region (110) and a border region (160). The light emitting substrate (100) includes a base (10), and a plurality of light emitting units (102) and a plurality of signal lines (30) located on the base (10). The light emitting units (102) are located in the light emitting region (110), and each includes a driving circuit (103) and at least one light emitting element (104). The plurality of light emitting units (102) are arranged into M rows along a first direction (D1) and into N columns along a second direction (D2) intersecting the first direction (D1). The plurality of signal lines (30) include N target signal lines (31) extending along the first direction (D1); the border region (160) includes a region of the light emitting substrate (100) located outside a first column of light emitting units (101), a region of the light emitting substrate (100) located outside an Nth column of light emitting units (101), and a region of the light emitting substrate (100) located outside a first row of light emitting units. A target signal line (31) for the first column of light emitting units (101) and/or the Nth column of light emitting units (101) include(s) a first extension section (311), a connection section (312) and a second extension section (313) connected in sequence. The first extension section (311) is connected with a driving circuit (103) and located in the border region (160). The first extension section (311), the connection section (312) and the second extension section (313) enclose a receiving region surrounding at least two groups of light emitting units (102).

    Abstract: A method for manufacturing a display backplane, a display backplate, and a display device are disclosed. The method includes: forming a planarization layer on one side of a substrate inside a pixel region, a partition region, and a perforation region; forming at least one girdle of annular passivation layer disposed around the perforation region on a surface, away from the substrate, of the planarization layer inside a portion of the partition layer; removing a portion of the planarization layer, inside the partition region, uncovered by the annular passivation layer and the planarization layer, inside the partition region, partially covered by the annular passivation layer, to obtain at least one girdle of annular isolation columns disposed between the substrate and the annular passivation layer and around the perforation region; and forming organic light-emitting elements on one side of the planarization layer away from the substrate to obtain the display backplane.
