A touch and display sensing integrated circuit and a touch display device using the same are provided. The touch display device includes a display and touch sensing integrated circuit and a glass substrate. The glass substrate includes touch/display common voltage electrodes, pixels, pads and conductive lines. Each pixel includes Q sub-pixels. The pads are electrically connected to the touch and display sensing integrated circuit. The Pth and (P+Q+1)th pads are electrically connected to the touch/display common voltage electrode through the corresponding conductive lines, respectively. The (P+1)th to (P+Q)th pads are electrically connected to 1st to Qth sub-pixels of a pixel through the corresponding conductive lines, respectively. The pads are arranged in a first direction, and the conductive lines, which are electrically connected to the pads in a second direction, are non-interlaced.
