LIGHTING DEVICE, DISPLAY DEVICE, AND TELEVISION RECEIVER

摘要

A lighting device (12) is configured in such a manner that a first circuit board (20a) and a second circuit board (20b) which have light sources (17) mounted thereon are adapted to be respectively arranged in predetermined arrangement and orientations on a first circuit board arrangement section (30a) and a second circuit board arrangement section (30b) which belong to a chassis (14). The first circuit board (20a) is provided with a first circuit board-side combining section (31a) which is combined with a chassis-side first combining section (32a) provided to the first circuit board arrangement section (30a), and the second circuit board (20b) is provided with a second circuit board-side combining section (31b) which is combined with a chassis-side second combining section (32b) provided to the second circuit board arrangement section (30b). When the first circuit board (20a) is allocated to the second circuit board arrangement section (30b), the first circuit board-side combining section (31a) cannot be combined with the chassis-side second combining section (32b).
