Abstract
Embodiments of the disclosure relate to touch display devices. The difference in parasitic capacitance due to the difference in length between the touch routing lines may be reduced by separately arranging touch electrode lines in the active area and connecting the touch routing line connected with each portion of a touch electrode line with the touch routing line connected with each portion of another touch electrode line. Therefore, it is possible to reduce loads and the differences in touch sensing depending on the connection structure and position of the touch routing line by driving the touch electrode line in a double-routing structure. By so doing, the performance of touch sensing may be enhanced.
