Light-emitting chip and light-emitting substrate

A light-emitting substrate, comprising:

• a drive back plate and a light-emitting chip disposed on a side of the drive back plate, the light-emitting chip comprising:
• a base substrate and at least two sub-light-emitting chips disposed on a side of the base substrate, wherein each sub-light-emitting chip comprises a first semiconductor layer, a second semiconductor layer and a light-emitting layer disposed between the first semiconductor layer and the second semiconductor layer, which are stacked;
• the sub-light-emitting chip further comprises a first electrode and a second electrode, wherein the first electrode is connected to the first semiconductor layer of the sub-light-emitting chip and the second electrode is connected to the second semiconductor layer of the sub-light-emitting chip.
