Abstract
A touch display device for preventing deterioration in image quality is structured such that a plurality of touch sensors is disposed on an encapsulation unit encapsulating a light-emitting element and includes a driving signal line, which includes a first driving signal line disposed below the encapsulation unit and a second driving signal line disposed above the encapsulation unit so as to be in contact with the first driving signal line to reduce line resistance of the driving signal line, thereby preventing deterioration in image quality.
Claims9
A touch display device comprising:
- a substrate including an active area and a bezel area adjacent to the active area;
- a light-emitting element on a substrate;
- an encapsulation unit on the light-emitting element;
- a plurality of touch sensors on the encapsulation unit;
- a first signal line in the bezel area, the first signal line disposed below the encapsulation unit;
- a second signal line in the bezel area, the second signal line electrically connected to the first signal line and disposed on the encapsulation unit;
- and
- a touch insulating film between the first signal line and the second signal line,
- wherein, in the bezel area, the first signal line and the second signal lines overlap each other with the touch insulating film interposed therebetween. and
- wherein the first signal line is a low-potential voltage line supplying low-potential voltage to the light-emitting element.
