Abstract:
A lighting device having a simplified connection configuration between light sources and a light source driver is provided. A backlight unit 12 according to this invention includes a plurality of LED boards 18 on which LEDs 17 are mounted. The LEDs 17 are light sources. Each LED board 18 includes a connection wiring pattern 27 electrically connected to the LEDs 17 and a through wiring pattern 28 not electrically connected to the LEDs 17. The connection wiring pattern 27 is connected to the through wiring pattern 28 on the other LED board 18. The connection wiring pattern 27 of each LED board 18 electrically connected to the LEDs 17 is electrically connected to the through wiring pattern 28 of the other LED board 18 not electrically connected to the LEDs 17.
