Abstract
An inorganic light-emitting diode substrate includes: a base, a plurality of epitaxial layer structures disposed on the base, a passivation layer, and a plurality of second electrodes disposed on a side of the passivation layer away from the base. The base includes a base substrate and a plurality of first electrodes disposed on the base substrate. The plurality of epitaxial layer structures are spaced apart, and each first electrode is coupled to one epitaxial layer structure. The passivation layer is made of photoresist. The passivation layer covers surfaces, away from the base, of the plurality of epitaxial layer structures, and fills gaps between the plurality of epitaxial layer structures. The passivation layer has a plurality of via holes, and each second electrode is coupled to one epitaxial layer structure through at least one via hole.
