1. A display device comprising:
a back chassis surrounded by a bezel;
a control board on a back surface of the back chassis;
a display panel surrounded by the bezel and positioned over a front surface of the back chassis, the display panel receives current from the control board;
a plurality of light source boards each having a wiring pattern including a plurality of wires that are positioned on the front surface of the back chassis;
a plurality of light-emitting elements disposed on each light source board and controlled by the control board;
board-side connectors each attached to a corresponding one of the plurality of light source boards to connect to board wires on the light source boards to drive the light-emitting elements;
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 each directly connected to the board-side connectors to provide the driving current to drive the light-emitting elements to the board-side connectors.
