Abstract
A light-emitting diode chip includes a light-emitting unit, a first electrode, an insulating layer, and a second electrode. The first electrode is disposed on the light-emitting unit. The insulating layer is disposed on the first electrode and the light-emitting unit, and has a through hole and a hole-defining wall. The hole-defining wall has a top peripheral edge that has two opposite end points. A projection of at least one of the end points of the top peripheral edge on the light-emitting unit falls outside a projection of a top surface of the first electrode on the light-emitting unit. The second electrode is disposed on the insulating layer and fills the through hole to electrically connect to the first electrode.
