Light-emitting element array

A light-emitting element array, comprising:

• a light-emitting element group that includes a plurality of first light-emitting elements and a plurality of second light-emitting elements that are arrayed in a planar manner to form a light-emitting element surface;
• the light-emitting elements constituting the light-emitting element group include a plurality of third light-emitting elements and a plurality of fourth light-emitting elements, the plurality of third light-emitting elements and the plurality of fourth light-emitting elements each having a mesa structure surrounded by a recessed portion, the recessed portion being separated from the light-emitting element surface and having a bottom surface parallel to the light-emitting element surface, an element isolation groove that electrically separates the plurality of third light-emitting elements and the plurality of fourth light-emitting elements from each other being provided in the bottom surface,
• the light-emitting element array further comprising:
• a first wire that extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of first light-emitting elements, and is not electrically connected to the plurality of second light-emitting elements;
• a second wire that extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of second light-emitting elements, and is not electrically connected to the plurality of first light-emitting elements;
• a third wire that extends in a direction parallel to the bottom surface, has a region of the bottom surface between the element isolation groove and the third light-emitting element and a region of the bottom surface between the element isolation groove and the fourth light-emitting element as viewed from a direction perpendicular to the bottom surface, overlaps with the element isolation groove, is electrically connected to the third light-emitting element, and is not electrically connected to the fourth light-emitting element;
• and
• a fourth wire that extends in a direction parallel to the bottom surface, has a region of the bottom surface between the element isolation groove and the third light-emitting element and a region of the bottom surface between the element isolation groove and the fourth light-emitting element as viewed from a direction perpendicular to the bottom surface, overlaps with the element isolation groove, is electrically connected to the fourth light-emitting element, and is not electrically connected to the third light-emitting element.
