Abstract: A display device includes a first substrate, light emitting elements, a second substrate, and a touch sensor on the second substrate. The touch sensor includes a first touch conductive layer on the second substrate, a touch insulating layer on the first touch conductive layer, and a second touch conductive layer on the touch insulating layer. The first touch conductive layer includes first sub-sensing electrodes, a connecting portion connecting the first sub-sensing electrodes adjacent to each other, and second sub-sensing electrodes. The second touch conductive layer includes a third sub-sensing electrode connected to one of the first sub-sensing electrodes through contact holes passing through the touch insulating layer, and a fourth sub-sensing electrode electrically connected to one of the second sub-sensing electrodes through contact holes passing through the touch insulating layer electrically connecting the second sub-sensing electrodes adjacent to each other.
