Touch structure, touch display panel and touch display device

A touch structure, comprising:

• an insulating layer;
• a first metal layer patterned and disposed on the insulating layer, the first metal layer comprising:
• a plurality of rows of first electrodes arranged in a first direction and a plurality of rows of second electrodes arranged in a second direction, wherein the second electrodes in a same row are electrically connected in sequence by a metal wire, the metal wire is formed by patterning the first metal layer, and the first direction is different from the second direction;
• a passivation layer disposed on the first metal layer, wherein a first recess is opened in the passivation layer corresponding to the first electrode;
• second metal layers partially filling the first recess of the passivation layer, and having an end electrically connected to the first electrode correspondingly;
• a third metal layer disposed on the passivation layer, and having opposite ends electrically connected to adjacent ones of the second metal layers, respectively,
• wherein the first recess forms a second recess after partially filling the second metal layers, and a bottom surface of the second recess is in contact with the first metal layer;
• and
• wherein a first inclined surface of the second recess forms an angle of 10 to 30 degrees with an upper surface of the first metal layer, and the first inclined surface is formed by the passivation layer.
