An electronic device is provided. The electronic device includes a substrate, a first light-shielding layer, a second light-shielding layer, a third light-shielding layer and an optical sensing element. The first light-shielding layer is disposed on the substrate and has a first opening. The second light-shielding layer is disposed on the first light-shielding layer and has a second opening. The third light-shielding layer is disposed on the second light-shielding layer and has a third opening. The optical sensing element is disposed on the substrate, and overlapped with the first opening. In addition, in a top-view diagram, centers of the first opening, the second opening and the third opening are separated from each other along a first direction, and the first direction is a line connecting a center of the first opening and a center of the third opening.
