Patent ID: 8390021

Claim:
A semiconductor light-emitting device having a substrate on which a semiconductor multilayer film is disposed, the semiconductor multilayer film having a layered structure in which a first conductive layer, a light-emitting layer and a second conductive layer are layered above the substrate from bottom to top in the stated order, and being divided into portions by grooves extending perpendicular to the substrate, each portion having a diode structure and serving as a light-emitting element, each light-emitting element having a hole in a central portion thereof in plan view, the hole penetrating through the second conductive layer and the light-emitting layer and reaching the first conductive layer, and comprising: a first electrode inserted in the hole and having a columnar shape, one end thereof being connected to the first conductive layer at the bottom of the hole, and the other end protruding from an opening of the hole; and a second electrode formed on the second conductive layer and having an annular shape surrounding the opening of the hole; and a set of at least two of the light-emitting elements are connected in series such that the first electrode of one light-emitting element is connected to the second electrode of another light-emitting element by a thin-film wire, and the semiconductor light-emitting device further comprises: a first power supply terminal connected to the first electrode of one light-emitting element that is located at one end of the series; and a second power supply terminal connected to the second electrode of another light-emitting element that is located at the other end of the series, wherein among the light-emitting elements, another set of light-emitting elements, which are different from the at least two light-emitting elements connected in series, are connected in series via a thin-film wire in the same manner as the at least two light-emitting elements, and the set of at least two light-emitting elements and the other set of light-emitting elements are parallely connected so as to be opposite in polarity.
