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

A touch panel, comprising:

• a substrate;
• touch electrodes on the substrate, wherein the touch electrodes comprise a first electrode in a first direction and a second electrode perpendicular to the first direction, and the first electrode comprises a plurality of first electrode blocks;
• and
• a plurality of bridge structures on the substrate, configured to electrically connect adjacent first electrode blocks of the plurality of first electrode blocks, wherein each of the plurality of bridge structures comprises:
• at least two metal bridge points, and an electrode connection bridge and a first protection layer overlying the at least two metal bridge points successively, wherein the electrode connection bridge comprises via holes corresponding to the metal bridge points in a one-to-one manner, and a pattern of an orthographic projection of the first protection layer on the substrate has a same shape as a pattern of an orthographic projection of the electrode connection bridge on the substrate;
• and two of the plurality of first electrode blocks respectively at two ends of each electrode connection bridge run respectively through via holes of the first protection layer and the via holes of the electrode connection bridge, and are electrically connected respectively with the metal bridge points.
