Organic light emitting display with touch sensor

A display device comprising:

• a light-emitting device disposed on a substrate;
• an encapsulation unit disposed on the light-emitting device;
• a plurality of touch electrodes disposed on the encapsulation unit, the plurality of touch electrodes comprising a plurality of first touch electrodes arranged in a first direction and a plurality of second touch electrodes arranged in a second direction that intersects the first direction;
• a plurality of bridges disposed on the encapsulation unit, the plurality of bridges comprising first bridges configured to interconnect the plurality of first touch electrodes and second bridges configured to interconnect the plurality of second touch electrodes;
• a routing line including a first routing line electrically connected to the plurality of first touch electrodes, and a second routing line electrically connected to the plurality of second touch electrodes,
• wherein the routing line is configured to have a structure in which a plurality of routing layers comprising a lower routing layer and an upper routing layer are stacked,
• wherein the upper routing layer and the lower routing layer overlap each other on at least a portion of the encapsulation unit, and
• wherein the lower routing layer and the upper routing layer have different widths.
