Abstract: 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.

Abstract: An electronic device having a sensing region and a non-sensing region includes a sensing element, a first light shielding layer and a second light shielding layer. The sensing element is disposed corresponding to the sensing region. The first light shielding layer includes at least one first opening corresponding to the sensing element. The second light shielding layer includes at least one second opening overlapped with the first opening. In a cross-section view, a boundary between the sensing region and the non-sensing region is at an outer side of an edge of a portion of the first light shielding layer, and a horizontal distance between an edge of a portion of the second light shielding layer and the sensing element is greater than or equal to a vertical distance between the portion of the second light shielding layer and the sensing element in a top-view direction of the electronic device.

Abstract: An electronic device is provided. The electronic device includes a substrate, an optical sensing element, a light-shielding structure, and a microlens. The substrate has a normal direction. The optical sensing element is disposed on the substrate. The light-shielding structure is disposed on the optical sensing element and includes a plurality of light-shielding layers. Each light-shielding layer includes an opening, and centers of the openings are arranged along a first direction and separated from each other. The microlens is disposed on the light-shielding layers and overlaps the opening of the uppermost light-shielding layer. The microlens guides light into an optical channel formed by the openings, so that the optical sensing element has a maximum response value for light with an incident angle that is greater than or equal to 10 degrees and less than or equal to 30 degrees relative to the normal direction.
