Touch panel, touch display panel and touch display device

The invention discloses a touch panel, a touch display panel and a touch display device and belongs to the technical field of display. The touch panel comprises a first substrate, multiple first electrodes, multiple second electrodes, a second substrate and multiple third electrodes, wherein the multiple first electrodes are arranged on a first surface of the first substrate in parallel at intervals and extend in a first direction; the multiple second electrodes are arranged on the first surface in parallel at intervals, are insulated from the multiple first electrodes and extend in a second direction, and the second direction and the first direction intersect; the second substrate is fixedly connected with the first substrate and parallel to the first substrate, and has a second surface opposite to the first surface; the multiple third electrodes are arranged on the second surface in parallel at intervals and extend in the second direction; the second electrodes and the third electrodes are alternately arranged in the second direction, and in a direction perpendicular to the first substrate, a plane where the second electrodes are located is parallel to a plane where the third electrodes are located. According to the touch panel, the touch display panel and the touch display device, floating touch is realized.
