Claim:
1. A fingerprint identification device formed on a substrate section, the substrate section having an upper side and a lower side, the fingerprint identification device comprising: a photoresist layer selectively disposed on the upper side or the lower side of the substrate section; a first coating layer disposed on one face of the photoresist layer distal from the substrate section; a first fingerprint identification electrode layer disposed on one face of the first coating layer distal from the photoresist layer, the first fingerprint identification electrode layer having multiple first fingerprint identification electrodes; a first protection layer overlaid on a part of the first fingerprint identification electrode layer; a second fingerprint identification electrode layer disposed on one face of the first protection layer distal from the first fingerprint identification electrode layer, the second fingerprint identification electrode layer having multiple second fingerprint identification electrodes; a second protection layer overlaid on a part of the second fingerprint identification electrode layer; a lead layer having multiple metal leads, the metal leads being selectively electrically connected with the first and second fingerprint identification electrode layers; and a flexible circuit board electrically connected with the first and second fingerprint identification electrode layers and the lead layer.
