Abstract: A photodetector is positioned so that imaginary lines perpendicular to an emission end surface of a first light-emitting element through first and second points, respectively, pass through the photodetector. The first and second points are two points at which an imaginary line parallel to the emission end surface through an inside of an outer edge of the first light-emitting element intersects the outer edge of the first light-emitting element in a top view. At least a part of a first wiring region is arranged in a first region between imaginary lines perpendicular to the emission end surface through third and fourth points, respectively. The third and fourth points are two points at which an imaginary line parallel to the emission end surface through an inside of an outer edge of the photodetector intersects the outer edge of the photodetector in the top view.
