Abstract:
1. A light-emitting device comprising: an element array portion including a plurality of element groups, each element group including a plurality of light-emitting elements arranged in a first direction, each light-emitting element having a structure such that a light-emitting layer lies between a first electrode and a second electrode, the element groups being arranged in a second direction perpendicular to the first direction; and an auxiliary interconnect that is formed of a material having a resistivity lower than the resistivity of the second electrode and that is electrically connected to the second electrode of each light-emitting element, wherein 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, and 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.
