A touch structure includes an insulating layer, first touch electrodes, second touch electrodes, and dummy electrodes that are insulated from each other. The second touch electrode includes second touch sub-electrodes and bridge portions, and every two adjacent second touch electrodes are electrically connected via a bridge portion. The second touch sub-electrodes and the bridge portions are disposed on two opposite sides of the insulating layer, and the second touch sub-electrodes and the first touch electrodes are disposed on a same side of the insulating layer. The dummy electrodes and the bridge portions are disposed on a same side of the insulating layer. Orthographic projections of the dummy electrodes on the insulating layer do not overlap with orthographic projections of the first touch electrodes and the second touch electrodes on the insulating layer.
