Abstract

Embodiments of the present invention provide a display substrate and a manufacturing method thereof, a display panel, and a display device, wherein the manufacturing method of the display substrate includes: providing a first substrate; the display substrate includes: a plurality of Pixel area; an anode, a light-emitting layer and a cathode arranged on each pixel area are formed on the first substrate; in each pixel area: the light-emitting layer includes a plurality of light-emitting units arranged at intervals, and the anode and the cathode are fully connected The conductive layer, the light-emitting unit is connected to the anode and the cathode respectively. The technical solution provided by the present invention sets the light-emitting layer as a plurality of light-emitting units arranged at intervals. When the anode corresponding to the pixel or the light-emitting layer is partially dirty or dusty, some well-bonded light-emitting units will still emit light, avoiding when When the anode or light-emitting layer corresponding to the pixel is partially dirty or dusty, the technical problem that the entire pixel is not bright is caused, which improves the yield rate and display effect of the display panel.
