Abstract

A light-emitting diode (LED) chip includes a plurality of epitaxial structures, at least one first electrode, and a plurality of second electrodes. Any two adjacent epitaxial structures of the plurality of epitaxial structures have a gap therebetween. Each epitaxial structure includes a first semiconductor pattern, a light-emitting pattern and a second semiconductor pattern stacked in sequence. First semiconductor patterns in at least two of the plurality of epitaxial structures are connected to each other to form a first semiconductor layer. A first electrode is electrically connected to the first semiconductor layer. Each second electrode is electrically connected to the second semiconductor pattern in at least one of the plurality of epitaxial structures.
