Title
(EN) LIGHTING DEVICE, DISPLAY DEVICE, TELEVISION RECEIVER AND METHOD OF MANUFACTURING LIGHTING DEVICE
Abstract
(EN)

It is an object of the present invention to provide a lighting device realizing cost reduction. A lighting device of the present invention includes a plurality of LEDs 16, an LED board 40 on which the LEDs 16 are mounted, and a chassis 14 to which the LED board 40 is attached. The LED board 40 has a rectangular frame-shape. The LED board 40 includes a first board 40A1 and a second board 40A2 attached to the chassis 14. The second board 40A2 having an outer shape smaller than that of the first board 40A1 may be provided inside the first board 40A1 in a plan view.
