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.

Abstract: Embodiments of the present disclosure are related to a display device, a turn-on state, a turn-off state of a driving transistor can be easily controlled by a control of a control voltage applied to a control gate electrode opposed to a driving gate electrode of the driving transistor and a non-light-emitting driving can be performed in a display driving. Furthermore, as the non-light-emitting driving is performed by the control voltage applied to the control gate electrode of the driving transistor, the non-light-emitting driving can be performed independently from a period in which a scan signal is applied, the non-light-emitting driving can be performed without affecting a display driving and a video response time of the display device can be improved.
