Touch sensor

A touch sensor comprising:

• a substrate;
• a plurality of first sensing electrodes arranged on the substrate and electrically connected in a first direction;
• a plurality of second sensing electrodes insulated from the plurality of first sensing electrodes and electrically connected in a second direction transverse to the first direction;
• a plurality of first conductive lines each connected to a first group of the first sensing electrodes and disposed in a first peripheral area of the substrate;
• a plurality of second conductive lines each connected to a second group of the first sensing electrodes and disposed in a second peripheral area of the substrate, the second peripheral area being opposite to the first peripheral area with respect to the first sensing electrodes;
• a plurality of third conductive lines connected to the second sensing electrodes;
• and
• a touch controller configured to analyze a touch input and connected to the first conductive lines, the second conductive lines, and the third conductive lines,
• wherein the first group of the first sensing electrodes and the second group of the first sensing electrodes are alternately arranged in the second direction,
• wherein the first conductive lines are spaced apart from each other in the first peripheral area, and
• wherein the second conductive lines are spaced apart from each other in the second peripheral area.
