Abstract
A fingerprint collection device and a display panel are provided. The fingerprint collection device includes: a base substrate, a driving circuit layer, a first passivation layer, a photodiode, a second passivation layer, and an electrode layer. A first electrode portion is electrically connected to the photodiode through a second via. A second electrode portion is electrically connected to a first signal trace and a second signal trace through a third via and a fourth via to form a bridge structure. Since the third via, the fourth via, and the second via are formed in same process, one process can be saved.
