<P>PROBLEM TO BE SOLVED: To provide a light-emitting device that suppresses deterioration in luminance, or the like, due to the light loss at the separate part surrounded by a Cu wiring layer which is a metal plate, and an insulating layer in the light-emitting device and which is equipped with a plurality of light-emitting elements. <P>SOLUTION: The light-emitting device is provided with a substrate, an insulating layer bonded onto the substrate, a pair of metal plates bonded onto the insulating layer, and a light-emitting element connected to a pair of the metal plates. A pair of the metal plates have the separate part, and the light-emitting element is installed on the metal plate, separated from the end contacting with the separate part. It is preferable that the distance D from the end contacting with the separate part to the light-emitting element be larger than the width d of the upper face of the light-emitting element, or identical to the width d of the upper face of the light-emitting element. <P>COPYRIGHT: (C)2009,JPO&INPIT |
