Abstract
An optical sensor includes pixels disposed in a substrate. A light collimating layer is disposed on the substrate and includes a transparent layer, a light-shielding layer, and transparent pillars. The transparent layer blanketly disposed on the substrate covers the pixels and the region between the pixels. The light-shielding layer is disposed on the transparent layer and between the transparent pillars. The transparent pillars penetrating through the light-shielding layer are correspondingly disposed on the pixels.
