    Abstract: A biosignal sensor includes a light-emitting element, a photo-detective element configured to detect a biosignal from light reflected from an in-vivo target, a first polarizer configured to selectively transmit light in a first polarization direction, and a second polarizer configured to selectively transmit light in a second polarization direction. The light-emitting element includes a first light-emitting element overlapped with the first polarizer in a vertical direction, the photo-detective element includes a first photo-detective element overlapped with the second polarizer in the vertical direction, the first light-emitting element and the first photo-detective element are parallel to each other along a first direction that is perpendicular to the vertical direction, and the first polarization direction and the second polarization direction are perpendicular to each other.
