Abstract
An optical sensor includes: first and second light receiving elements on a semiconductor substrate; a light blocking film over the semiconductor substrate via a light transmitting film; and first and second openings corresponding to the light receiving elements and disposed in the light blocking film. First and second virtual lines are defined to extend from the centers of the first and second light receiving elements and pass through the centers of the first and second openings, respectively. At least one of elevation angles and left-right angles of the first and second virtual lines are different. The photosensitive area of the first light receiving element is larger than the aperture area of the first opening. The photosensitive area of the second light receiving element is larger than the aperture area of the second opening.
