Claim 13:
14. A sensing device, comprising:
a first substrate;
a first sensing element disposed over the first substrate and includes:
a first electrode;
a second electrode disposed over the first electrode; and
a sensing layer disposed between the first electrode and the second electrode;

a first light-shielding layer disposed on the first sensing element and having a first opening, wherein the first opening overlaps the first electrode, the sensing layer and the second electrode;
a second light-shielding layer disposed on the first light-shielding layer and having a light-receiving region and a light-receiving edge adjacent to the light-receiving region; and
an insulating layer disposed between the first light-shielding layer and the second light-shielding layer,
wherein a ratio of a spacing between a side of an orthographic projection of the first opening on the second light-shielding layer farthest from the light-receiving edge and the light-receiving edge to a maximum spacing between the second light-shielding layer and the sensing layer is 0.3 to 1.8.
