Abstract
A light-emitting diode element comprises a semiconductor wafer including a pair of a p-type semiconductor region and an n-type semiconductor region forming a pn junction, an inclined first electrode provided on at least one of the peripheral edges of the surface of one of the semiconductor regions in the semiconductor wafer, and a flat second electrode provided on the surface of the other semiconductor region. A light-emitting diode device is provided in which a plurality of such light-emitting diode elements are respectively received in a plurality of openings of a substrate having a first wiring conductor group and a second wiring conductor group electrically connected to the first and second electrodes respectively of the light-emitting diode elements by a low-melting metal. Thus, these light-emitting diode elements can be mounted on the single substrate in a high package density, and the light-emitting diode device of simple construction can be easily assembled.
