Touch display device

Abstract:

Embodiments of the present disclosure relate to a touch display device, in which touch routing lines arranged in a non-active area do not overlap signal lines supplying a signal for driving a display, and in which the size of the area in which a connection electrode, which is positioned between the touch routing lines and the signal lines, overlaps the signal lines is reduced, thereby reducing direct and indirect noise due to the signal lines. In addition, the noise due to the signal lines can be dispersed through a shielding electrode by arranging the shielding electrode, to which a constant voltage is applied, in an opening in the connection electrode, thereby further reducing the noise of a touch sensing signal and improving touch sensing performance thereof.
