Abstract: A light-emitting element array includes multiple light-emission instruction units arranged in a first direction; a first light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the light-emitting element groups are arranged in a direction intersecting the first direction; a second light-emitting element group row including light-emitting element groups each including a multiple light-emitting elements such that the second light-emitting element group row is arranged along the first light-emitting element group row in the first direction; and a multiple wiring lines that connect the multiple light-emission instruction units to the light-emitting element groups in the first light-emitting element group row and the light-emitting element groups in the second light-emitting element group row to provide a light-emission instruction. The multiple wiring lines are connected such that in response to the multiple light-emission instruction units sequentially providing a light-emission instruction in the first direction, the light-emitting element groups in the first light-emitting element group row sequentially emit light in the direction intersecting the first direction and, after turning on of the first light-emitting element group row is completed, the light-emitting element groups in the second light-emitting element group row sequentially emit light in the direction intersecting the first direction.

Abstract: A light-emitting device includes a light-emitting unit. The light-emitting unit includes an array of multiple light-emitting element groups, each including multiple light-emitting elements. In the light-emitting unit, the multiple light-emitting element groups are sequentially driven along the array such that, for each of the multiple light-emitting element groups, the multiple light-emitting elements included in the light-emitting element group are concurrently set to a state of emitting light or a state of not emitting light.
