    Abstract: An optical sensor includes: a sensing unit including a first sensing electrode, a second sensing electrode spaced apart from the first sensing electrode, and a sensing layer between the first sensing electrode and the second sensing electrode, the sensing layer containing amorphous silicon and germanium (Ge) ions impregnated in the amorphous silicon; and an optical pattern unit on the sensing unit and including a light shielding pattern and a plurality of transmission patterns in the light shielding pattern, wherein the sensing layer includes a first region, a second region, and a third region sequentially arranged from a boundary between the second sensing electrode and the sensing layer toward the first electrode, and a concentration of the germanium (Ge) ions in the amorphous silicon is relatively higher in the second region than in the first region and the third region.
