Touch display panel, method for fabricating the same, and display device

A touch display panel, comprising a substrate, an encapsulation cover plate, and organic light-emitting elements, a printed circuit board, and organic light-emitting element lead-out lines connected with the organic light-emitting elements, the organic light-emitting elements, the printed circuit board, and the organic light-emitting element lead-out lines are arranged on a side of the substrate facing the encapsulation cover plate, wherein the organic light-emitting elements are electrically connected with the printed circuit board through the organic light-emitting element lead-out lines, wherein the touch display panel further comprises:

• first spacers, and touch signal lines overlying the first spacers, the first spacers and touch signal lines are arranged successively on a side of the encapsulation cover plate facing the substrate;
• and
• second spacers corresponding to the first spacers, and metal lines overlying the second spacers, the second spacers and metal lines are arranged on the side of the substrate facing the encapsulation cover plate, wherein the metal lines are connected with the printed circuit board, and the metal lines are electrically connected with the touch signal lines overlying the first spacers.
