ABSTRACT:
A light-emitting device includes an element array portion and an auxiliary interconnect. The element array portion includes a plurality of element groups. Each element group includes a plurality of light-emitting elements arranged in a first direction. Each light-emitting element has a structure such that a light-emitting layer lies between a first electrode and a second electrode. The element groups are arranged in a second direction perpendicular to the first direction. The auxiliary interconnect is formed of a material having a resistivity lower than the resistivity of the second electrode and is electrically connected to the second electrode of each light-emitting element. The plurality of element groups include a first element group and a second element group adjacent to each other and a third element group adjacent to the opposite side of the second element group from the first element group. The auxiliary interconnect extends in the first direction in a gap between the first element group and the second element group but is not formed in a gap between the second element group and the third element group.
