The invention provides a touch display device and a manufacture method of the touch display device as well as a display device, belonging to the field of a touch screen display device. The touch display device comprises a bi-grid array base plate and a touch signal position judgment circuit. The touch display device further comprises a plurality of optical sensing units arranged on the bi-grid array base plate; the optical sensing units are used for generating output signals according to the received illumination variable quantity, and transmitting the output signals to the touch signal position judgment circuit through optical sensing signal wires, and the touch signal position judgment circuit is used for judging the touch position according to the received output signals; and the optical sensing signal wires are arranged between two lines of adjoining sub-pixels, and data wires are not arranged between the two lines of the adjoining sub-pixels. According to the technical scheme of the invention, the touch accuracy and precision of optical touching and sensing can be improved, and the aperture opening ratio of a display panel can not be influenced.
