Light-emitting assembly and display substrate

A display substrate, comprising:

• a drive backplane and a plurality of light-emitting assemblies, wherein
• each of the plurality of light-emitting assemblies comprises:
• a plurality of light-emitting units, wherein each of the plurality of light-emitting units comprises a first semiconductor layer, a light-emitting layer, and a second semiconductor layer that are laminated;
• a color-converting portion, disposed on a side, away from the light-emitting layer, of the first semiconductor layer;
• a common electrode layer, disposed between the first semiconductor layer and the color-converting portion, electrically connected to the first semiconductor layer, and connected to at least two of the plurality of light-emitting units;
• first electrodes, disposed on a side, away from the light-emitting layer, of the second semiconductor layer and electrically connected to the second semiconductor layer, the first electrodes being in one-to-one correspondence with the plurality of light-emitting units;
• and a first encapsulation layer, at least enclosing sidewalls of the plurality of light-emitting units;
• wherein in a thickness direction of the light-emitting layer, a distance between the first electrodes and the common electrode layer is less than a span of the first encapsulation layer in the thickness direction;
• and
• the drive backplane is configured to bear the plurality of light-emitting assemblies, and supply drive signals to the plurality of light-emitting assemblies.
