Abstract
In a touch display device, an electrode pattern is arranged on an area overlapping a touch electrode and a touch routing line which are disposed on an active area. Thus a touch sensor structure can be implemented while improving visibility of a display panel.
Claims19
A touch display device, comprising:
- a plurality of light-emitting elements disposed on an active area of a display panel;
- an encapsulation layer disposed on the plurality of light-emitting elements;
- a plurality of touch electrodes disposed on the encapsulation layer;
- a plurality of dummy electrodes on a same layer as the plurality of touch electrodes, the plurality of dummy electrodes separated from the plurality of touch electrodes;
- a plurality of touch routing lines electrically connected to the plurality of touch electrodes;
- and
- at least one dummy pattern disposed between the encapsulation layer and the plurality of touch electrodes and the plurality of dummy electrodes such that the at least one dummy pattern is on a different layer than the plurality of dummy electrodes and the plurality of touch electrodes, the at least one dummy pattern overlapping at least a portion of the plurality of touch electrodes and at least a portion of the plurality of dummy electrodes.
