<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of normally emitting a light, even if the direction of the light-emitting element is interchanged with respect to relevant electrodes capable of suppressing the manufacturing cost, and to provide a method for manufacturing the device. <P>SOLUTION: In a filament-shaped light-emitting element 5 of the light-emitting device, a P-type first region 6 and a P-type third region 8 are respectively arranged on both sides of an N-type second region 7. Accordingly, even if respective connections of the first and third regions 6, 8 of the filament-shaped light-emitting element 5 to a first and third electrodes 1, 3 are interchanged, since respective diode polarities with respect to the first and third electrodes 1, 3 are not interchanged, normal light emission becomes possible. Hence, the manufacturing process is allowed to have respective connections of the first and third regions 6, 8 to the first and third electrodes 1, 3 exchanged; and even if the connections become opposite, neither the mark nor the shape for identifying the direction of the filament-shaped light-emitting element 5 becomes necessary, and the manufacturing process can be simplified and the manufacturing cost is suppressed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
