A touch display device is provided. The device includes an array substrate and a color substrate opposite to the array substrate; the array substrate is provided with a plurality of touch driving electrodes; a plurality of sub-pixels defined by a plurality of source lines and a plurality of gate lines insulated from and intersected with the plurality of source lines. Sub-pixels of each row are driven in a time division manner by corresponding two of the plurality of gate lines. The plurality of source lines include data lines and touch driving lines. Adjacent two sub-pixels, connected to a same data line, in a same row are connected to two different gate lines. Adjacent two sub-pixels, connected to a same gate line, in a same row are connected to two different data lines.
