Abstract:
1. A light emitting device comprising: a plurality of LED chips comprising a first LED chip and a second LED chip, each of the plurality of LED chips comprising: a substrate; a light emitting region that is formed on the substrate; an electrode that is connected to the light emitting region and is formed on the substrate; one or more through-holes that penetrate the substrate; and one or more wirings, each passing through the one or more through-holes of the first LED chip and the one or more through-holes of the second LED chip that is adjacent to the first LED chip, and that electrically connecting the electrode of the first LED chip and the electrode of the second LED chip, wherein with regard to each of the first LED chip and the second LED chip, a tip-end part of each of the one or more wirings passing through the one or more through-holes has, at a cross section when cut at a plane that is parallel with a first principle surface of the substrate, a larger cross-sectional area than a cross-sectional area of each of the one or more wirings inside the one or more through-holes, the substrate of the first LED chip and the substrate of the second LED chip are separated, and the each of the one or more wirings links the first LED chip and the second LED chip.
