Touch display device

A touch display device comprising:

• a substrate;
• a plurality of pixel electrodes each disposed at each of a plurality of subpixel areas on the substrate;
• a common electrode disposed on the plurality of pixel electrodes and to which a common voltage is applied;
• a plurality of light-emitting elements disposed between the plurality of pixel electrodes and the common electrode;
• an encapsulation layer disposed to cover the common electrode;
• a touch sensor including n first touch electrode lines and m second touch electrode lines disposed on the encapsulation layer in a display area, where n is a natural number greater than or equal to two, and m is a natural number greater than or equal to two, wherein each of the n first touch electrode lines and the m second touch electrode lines includes one or more touch sensor metals;
• a touch pad part disposed in a first non-display area, which is located at an outer periphery of the display area in a first direction, among non-display areas that are outer areas of the display area and including 2n first touch pads and 2m second touch pads;
• 2n first touch routing lines coming downward along an inclined surface of the encapsulation layer and electrically connecting one ends and the other ends of the n first touch electrode lines to the 2n first touch pads disposed in the first non-display area, respectively;
• and
• 2m second touch routing lines coming downward along the inclined surface of the encapsulation layer and electrically connecting one ends and the other ends of the m second touch electrode lines to the 2m second touch pads disposed in the first non-display area, respectively,
• wherein two or more first touch routing lines among the 2n first touch routing lines and two or more second touch routing lines among the 2m second touch routing lines pass through a second non-display area located at an outer periphery of the display area in a second direction,
• wherein the two or more first touch routing lines passing through the second non-display area include the touch sensor metal and are disposed to overlap with the common electrode extending from the display area to the second non-display area,
• wherein the two or more second touch routing lines passing through the second non-display area include an upper second touch routing lines and a lower second touch routing lines,
• wherein the upper second touch routing lines disposed on a first layer in the second non-display area, and the lower second touch routing lines disposed below the first layer in the second non-display area,
• wherein the upper second touch routing lines include the touch sensor metal, and the lower second touch routing lines include a first metal different from the touch sensor metal, and
• wherein the upper second touch routing lines and the lower second touch routing lines does not overlap with the common electrode extended from the display area to the second non-display area.
