LED chip, display device and electronic equipment

The invention provides an LED chip. The LED chip comprises a conductive substrate, a light-emitting structure and a common electrode. The light emitting structure includes a first quantum dot, a semiconductor portion, and a separation portion. The semiconductor part is bonded with the conductive substrate, the semiconductor part comprises a first pixel unit, a second pixel unit and a third pixel unit, and the separation part is arranged on the conductive substrate to isolate the first pixel unit, the second pixel unit and the third pixel unit. The first quantum dots are matched with the first pixel units to convert colors emitted by the first pixel units, and the first pixel units, the second pixel units and the third pixel units are electrically connected with the conductive substrate. The common electrode is electrically connected with the first pixel unit, the second pixel unit and the third pixel unit. The conductive substrate can be energized with the common electrode such that current passes through the
