Touch sensor and image display device including the same

A touch sensor, comprising:

• a base layer;
• a first electrode layer disposed on the base layer, the first electrode layer comprising:
• a plurality of first sensing electrode rows extending in a first direction parallel to a top surface of the base layer;
• and
• first traces branched from each of the first sensing electrode rows and alternately distributed on both lateral portions of the base layer;
• a second electrode layer disposed on the base layer, the second electrode layer disposed at a different layer from that of the first electrode layer,
• where in the second electrode layer comprising:
• a plurality of second sensing electrode columns extending in a second direction that is parallel to the top surface of the base layer and intersects the first direction;
• second traces branching from the second sensing electrode columns;
• and
• an intermediate trace electrically connected to each of the first traces, the intermediate trace comprising a first portion connected to each of the first traces and a second portion bent from the first portion,
• wherein a width of the first portion of the intermediate trace is greater than a width of the second portion of the intermediate trace and satisfies Equation 1 below:
• 0.1P≤W1<2P [Equation 1]
• wherein W1 represents the width of the first portion of the intermediate trace, and P is a pitch of the first sensing electrode rows.
