摘要:
A lighting device including an electroluminescent (EL) material is connected to an external power supply easily and the convenience is improved. In a lighting device having a light-emitting element including an electroluminescence (EL) layer, a housing including a light-emitting element has a terminal electrode electrically connected to the light-emitting element on a peripheral end portion. The terminal electrode provided on the housing so as to be exposed to the outside is in contact with a terminal electrode for the external power supply, so that the external power supply and the light-emitting element are electrically connected to each other and power can be supplied to the lighting device.
