Abstract: Provided are a touch sensor and a display device. The touch sensor includes a base layer; first electrode members arranged on the base layer in a first direction and spaced apart from one another in a second direction intersecting the first direction, each of the first electrode members including a first opening and a plurality of first touch electrodes electrically connected to one another in the first direction; second electrode members arranged on the base layer in the second direction and spaced apart from one another in the first direction, each of the second electrode members including a second opening and a plurality of second touch electrodes electrically connected to one another in the second direction intersecting the first direction; a first strain gauge including a portion located in the first opening and disposed in a first electrode row among electrode rows of the first electrode members; a second strain gauge including a portion located in the second opening and disposed in a first row among rows of the second touch electrodes; a first signal line connected to one end of the first strain gauge; a second signal line connected to another end of the first strain gauge and spaced apart from the first signal line; a third signal line connected to one end of the second strain gauge and the second signal line; and a fourth signal line connected to another end of the second strain gauge and spaced apart from the third signal line.
