1. A sensing device, comprising:
a first substrate;
a first sensing element disposed over the first substrate;
a first light-shielding layer disposed on the first sensing element and having a first opening, wherein the first opening completely overlaps the first sensing element;
a second light-shielding layer disposed on the first light-shielding layer and including an upper light-shielding part and a lateral light-shielding part, wherein the upper light-shielding part overlaps the first light-shielding layer and has a second opening, and the lateral light-shielding part is separated from the upper light-shielding part; and
an insulating layer disposed between the first light-shielding layer and the second light-shielding layer, wherein the lateral light-shielding part covers a sidewall of the insulating layer.
