<P>PROBLEM TO BE SOLVED: To provide semiconductor light-emitting element, light-emitting device, illumination device, display device, signal light unit and road information device, capable of protecting a light-emitting diode (LED) from static electricity and overvoltage without an external protection element. <P>SOLUTION: A light-emitting element 100 has a separate formation of LED structures, each composed of laminated semiconductor layers of an n-type semiconductor layer (LED structure) 20, an active layer (not shown) and a p-type semiconductor layer 3, respectively disposed in the vicinity of corners on one diagonal of a rectangular-shaped substrate 1. Further, in the vicinity of corners on the other diagonal of the substrate 1, bonding electrodes 71, 71 circular shaped in a plan view are formed. In the vicinity of edges mutually opposite to the substrate 1, resistance elements composed of n-type semiconductor layers 22, 21 are formed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
