Optical sensing device

An optical sensing device, comprising:

• a sensing pixel comprising a sensing circuit and a sensing element electrically connected to the sensing circuit;
• a driving circuit electrically connected to the sensing circuit;
• a first light shielding layer comprising at least one first opening corresponding to the sensing element;
• a second light shielding layer comprising at least one second opening overlapped with the at least one first opening in a top-view direction of the optical sensing device, wherein the second light shielding layer is overlapped with the driving circuit in the top-view direction;
• and
• a third light shielding layer comprising at least one third opening overlapped with the at least one first opening in the top-view direction,
• wherein an edge of the second light shielding layer corresponds to a peripheral region of the optical sensing device, and a horizontal distance between the edge of the second light shielding layer and the sensing pixel is greater than a horizontal distance between the edge of the second light shielding layer and the driving circuit,
• wherein the second light shielding layer is overlapped with the third light shielding layer in the peripheral region, and a boundary between the peripheral region and a sensing region of the optical sensing device is at an outer side of an edge of the first light shielding layer,
• wherein another edge of the second light shielding layer adjacent to the sensing pixel extends outward from the sensing pixel by a second extension distance, a vertical distance between the second light shielding layer and the sensing pixel in the top-view direction is defined as a second spacing, and the second extension distance is greater than or equal to the second spacing.
