  • Patent number: 11782567
    Abstract: Embodiments of the present disclosure are related to a touch display device, as a touch sensor connecting pattern for a connection between touch sensors or a connection between a touch sensor and a touch routing line is disposed by using a same material with a voltage line disposed on a subpixel. Thus, an electrode structure for a touch sensing can be implemented while reducing a manufacturing process. Furthermore, as the voltage line is disposed to overlap at least a part of the touch sensor and the touch routing line, a performance of the touch sensing can be improved by reducing an influence that a parasitic capacitance by a driving of a light-emitting element affects the touch sensing.
