Abstract
Embodiments of the present disclosure relate to a touch sensing unit and a touch display device, in which touch routing lines can be arranged so as not to overlap signal lines supplying a signal for driving a display and the area of an electrode located between the signal line and in which the touch routing line can be reduced, thereby reducing parasitic capacitance between the signal line and the touch routing line. In addition, it is possible to further reduce noise due to the signal lines and to improve the performance of touch sensing by distributing noise due to the signal lines through touch dummy electrodes positioned between the touch electrodes and the touch routing lines so as to overlap the signal lines.
