[Object] To make occurrence of luminance unevenness difficult even if a failure or something occurs to a solid-state light-emitting element (LED) in an open mode in a light-emitting device using a plurality of LEDs. [Means for Settlement] A light-emitting device 1 includes a plurality of LED groups 2G each having a plurality of LEDs 2 arranged proximately and connected in series, the LEDs 2 in each LED group 2G are configured so as to be equal in an inter-element potential difference, and the LED groups 2G are connected in parallel and configured so as to be equal in a potential difference. With this configuration, even if a failure or something occurs to one LED 2 in an open mode, current flows to the other LEDs 2. Due to this, the LED group 2G is not extinguished as a group and luminance unevenness can be suppressed. |
