A touch display device including a touch display panel and a data line driving circuit is provided. The touch display panel includes a plurality of pixels and a first shift register unit. The first shift register unit provides a first shifted signal to a first portion of the pixels. A first transistor receives a clock signal, is coupled to an output node, and outputs the first shifted signal. A second transistor receives a first trigger signal, is coupled to the first transistor. A third transistor is coupled to the second transistor, receives a first operation voltage and a second trigger signal. A fourth transistor is coupled to the first source, receives a second operation voltage and the second trigger signal. A capacitor is coupled between the first transistor and stacked by a first metal layer, a second metal layer, and a third metal layer. |
