The present invention disclose a touch electrode structure and a fabricating method thereof, a capacitive touch device and a touch display device to improve the touch linearity and the report rate of the capacitive touch device. The touch electrode structure provided by the embodiments of the present invention comprises a plurality of electrode assemblies and a plurality of electrode pins for connecting a touch circuit. Wherein, each electrode assembly comprises two electrodes which are disposed at the same layer, insulated from each other and cross with each other complementarily, and each electrode comprises at least two sub-electrodes which are in mutual electrical connection with each other. The sub-electrodes of different electrodes of each electrode assembly are spaced apart from each other one by one, and each electrode is connected with an electrode pin.
