1. A display device with a touch detection device, comprising
scan lines each extending overall in a first direction;
signal lines each extending overall in a second direction crossing the first direction;
display elements;
thin film transistors each connected to a corresponding one of the display elements, the thin film transistors each being surrounded by the scan lines and the signal lines; and
touch detection electrodes including a first thin metal wire, a second thin metal wire, a third thin metal wire, and a fourth thin metal wire that are opposed to the display elements,
wherein
the first thin metal wire, the second thin metal wire, the third thin metal wire, and the fourth thin metal wire each are straight line,
the first thin metal wire and the fourth thin metal wire each extend in a third direction different from the first and second directions,
the second thin metal wire and the third thin metal wire each extend in a fourth direction different from the first, second, and third directions,
the first thin metal wire intersects the third thin metal wire,
the second thin metal wire intersects the fourth thin metal wire,
the first thin metal wire is connected to the second thin metal wire at a first connection point,
the third thin metal wire is connected to the fourth thin metal wire at a second connection point, and
the first thin metal wire, the second thin metal wire, the third thin metal wire, and the fourth thin metal wire each intersect the scan lines.
