Abstract: An optical sensor includes an optical layer disposed on a substrate, and a light shielding layer disposed on the optical layer, wherein the light shielding layer includes a first opening that partially exposes the optical layer. The optical sensor also includes a polymer material layer that fills the first opening, wherein a top surface of the polymer material layer is higher than a top surface of the light shielding layer. The optical sensor further includes an adhesive layer disposed on the light shielding layer and the polymer material layer, and a surface component disposed on the adhesive layer.
