BONDING REGION STRUCTURE, MANUFACTURING METHOD THEREFOR, PANEL, AND TOUCH DISPLAY DEVICE

A bonding region structure, a manufacturing method therefor, a panel, and a touch display device. The bonding region structure comprises: a substrate; a light blocking layer disposed on the surface of the substrate; a patterned electrode, said patterned electrode being disposed on the light blocking layer on the side away from the substrate; a metal connecting portion, said metal connection portion being disposed on the surface of one side, away from the light blocking layer, of the patterned electrode for bonding with and connecting to an external circuit; and an etching stop portion, said etching stop portion at least being provided on the light blocking layer on the side away from the substrate at a region where the patterned electrode is not provided, so as to cover the part of the light blocking layer exposed by the patterned electrode. La présente invention concerne une structure de région de liaison et son procédé de fabrication, un panneau et un dispositif d'affichage tactile. La structure de région d
