摘要

A backlight device according to the present invention is provided with: a chassis having a bottom plate 22a and a side plate; LED substrates 25 disposed on the bottom plate 22a of the chassis in a manner so that one end surface of the LED substrates and the side plate face each other; LEDs disposed on the LED substrates 25 with the obverse side as the light exit side; a wiring pattern 35 disposed on the LED substrates 25; a first connector 31 connected to the wiring pattern 35 and disposed on the end on the side provided with the one end surface among the ends of the LED substrates 25; a second connecting member that is electrically connected to the first connector 31 with the direction of connection being a direction that is along the plate surface of the bottom plate 22a, forming in a plan view an angle with the first side edge 22a1 that faces the one end surface, and facing the first side edge 22a1 from the reverse side from the first side edge 22a1 sandwiching the first connector 31; and a power supply wiring line 38 that is electrically connected to the second connector 32.

主权项

1. An illumination device, comprising:
a housing member that has a bottom plate and a side plate that rises from a side edge of said bottom plate, the housing member having an aperture on top to transmit light; a light source substrate disposed on the bottom plate of the housing member such that one end face of the light source substrate faces the side plate; light sources disposed on the light source substrate such that light is emitted upward; patterned wiring disposed on the light source substrate and electrically connected to the light sources; a first connecting member electrically connected to the patterned wiring and disposed on, of end portions of the light source substrate, an end portion that has said one end face; a second connecting member electrically connected to the first connecting member in a connecting direction along a plane of the bottom plate of the housing member, the connecting direction also being, in a plan view, a direction directed toward said side edge of the bottom plate from a side opposite to said side edge across the first connecting member at an angle with respect to said side edge; and a power supply wiring line electrically connected to the second connecting member and supplying power to the light sources through the second connecting member, the first connecting member, and the patterned wiring, wherein the bottom plate has a horizontally long rectangular shape having a pair of first side edges along a short side direction of the bottom plate and a pair of second side edges along a long side direction of the bottom plate, said side edge from which said side plate rises being one of the first side edges, wherein a plurality of said light source substrates are disposed on the bottom plate, and the respective one end faces of the light source substrates face the side plate that rises from said side edge, wherein the plurality of light source substrates each have the first connecting member disposed thereon, wherein a plurality of said first connecting members each have the second connecting member connected thereto, and wherein all of a plurality of said second connecting members are connected to the respective first connecting members in the same connecting direction as each other.
