Abstract:
1. A bonding structure, comprising: a first substrate; a plurality of first bonding pads located on the first substrate; a second substrate disposed to partially face the first substrate; a plurality of second bonding pads located on the second substrate with one side; and the second bonding pads partially overlapped with the first bonding pads with the other side to form a bonding region; and a peripheral region located in the periphery of the bonding region; an anisotropic conductive film located between the first bonding pads and the second bonding pads; a plurality of first conducting wires respectively connected to the first bonding pads; and a protective layer overlaid on the first conducting wires; and at least a first groove structure located in the peripheral region and at least a second groove structure in the bonding region; wherein the first groove structure is obtained by forming a plurality of grooves in the border of the protective layer; and the first groove structure is located in the peripheral region and adjacent to the anisotropic conductive film in the bonding region; and wherein the second groove structure is obtained by forming a plurality of grooves in the border of the second substrate and located between two adjacent second bonding pads.
