Abstract
Disclosed is an organic light emitting display device with a touch sensor. The display device has a touch sensor that is directly disposed on a sealing part, thus removing the necessity of an additional adhesion process, simplifying a manufacturing process and reducing manufacture cost. In addition, the display device with the touch sensor includes a display cover electrode of a display pad that is made of a same material as a conductive layer included in the touch sensor, thus preventing damage to the display pad electrode.
Claims22
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;
- color filters on the encapsulation unit;
- a plurality of bridges disposed on the encapsulation unit, the plurality of bridges comprising first bridges that interconnect the plurality of first touch electrodes and second bridges that interconnect the plurality of second touch electrodes;
- and
- 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 at least one of the first bridge and the second bridge overlaps a boundary of each of the color filters.
