Display device

Disclosed is a touch panel-equipped display device capable of suppressing an increase in the number of wires and improving detection resolution. A touch panel-equipped display device includes scanning lines and detection lines. The detection lines include first main detection lines, second main detection lines, first one-side sub-detection lines, and first other-side sub-detection lines. Each of the second main detection lines is arranged between adjacent first main detection lines. The first one-side sub-detection lines are connected together, and each first one-side sub-detection lines is arranged between the corresponding first main detection line and the second main detection line adjacent to one side of the corresponding first main detection line. The first other-side sub-detection lines are connected together, and each first other-side sub-detection lines is arranged between the corresponding first main detection lines and the second main detection line adjacent to the other side of the corresponding fi
