Abstract:
The present disclosure relates to a touch display device, and more specifically, relates to a touch display device having a bottom emission structure. According to the touch display device, by disposing a touch electrode and a touch planarization layer between a substrate and a thin film transistor, a touch sensing function can be implemented without affecting the disposing of components for display driving. Further, by disposing a shielding electrode to which a constant voltage or a signal equal to a touch driving signal is applied between the touch electrode and a light emitting element, a noise of a touch sensing signal caused by display driving can be reduced and the performance of touch sensing performed together with the display driving can be improved.
