1. A display device comprising:
a display area;
a first dam surrounding the display area;
a second dam surrounding the first dam;
a first sensor electrode and a second sensor electrode overlapping the display area;
a first sensor wiring over the first dam and electrically connected to the first sensor electrode;
a second sensor wiring over the first dam and electrically connected to the second sensor electrode;
a first wiring under the second dam and electrically connected to the first sensor wiring at a first contact portion; and
a second wiring under the second dam and electrically connected to the second sensor wiring at a second contact portion, wherein
the first contact portion and the second contact portion are located between the first dam and the second dam,
the second dam has an overlap with the first wiring at a first overlap portion,
the second dam has an overlap with the second wiring at a second overlap portion,
the second dam has a second intermediate portion between the first overlap portion and the second overlap portion,
the first dam has an overlap with the first sensor wiring at a third overlap portion,
the first dam has an overlap with the second sensor wiring at a fourth overlap portion,
the first dam has a first intermediate portion between the third overlap portion and the fourth overlap portion, and
a third length between the first intermediate portion of the first dam and the second intermediate portion of the second dam is shorter than a first length between the first overlap portion of the second dam and the third overlap portion of the first dam and a second length between the second overlap portion of the second dam and the fourth overlap portion of the first dam.
