1. A display device comprising:
a casing; and
a lighting device in the casing,
wherein the lighting device comprising:
a plurality of light source boards each having a wiring pattern including a plurality of wires;
a plurality of light-emitting elements disposed on each light source board which are controlled by a control board that controls switching between on and off of the light-emitting elements;
board-side connectors each attached to a corresponding one of the plurality of light source boards;
a flexible flat cable that has a multi-core structure including a flat-shaped insulator and a plurality of conductors aligned in a direction orthogonal to a thickness direction of the insulator, and is connected at one end to the control board; and
a plurality of cable-side connectors connected to the flexible flat cable and connected to the board-side connectors,
wherein some conductors of the plurality of conductors are electrically connected to the wires at each of the plurality of light source boards via a corresponding one of the cable-side connectors and a corresponding one of the board-side connectors,
wherein
each cable-side connector is provided with a plurality of connection terminals, connection holes for exposing some conductors of the plurality of conductors are formed in the insulator, and
some connection terminals of the plurality of connection terminals are inserted into the connection holes to be connected to the conductors.
