A liquid ejecting device includes a plurality of liquid ejecting heads reciprocally movable in a main scanning direction and arrayed in the main scanning direction. Each of the plurality of liquid ejecting heads include a liquid ejecting portion configured to eject liquid. The plurality of liquid ejecting heads includes: a first endmost liquid ejecting head; and a second endmost liquid ejecting head. The first endmost liquid ejecting head constitutes one end in the main scanning direction of the plurality of liquid ejecting heads. The second endmost liquid ejecting head constitutes another end in the main scanning direction of the plurality of liquid ejecting heads. The liquid ejecting portion of at least one of the first endmost liquid ejecting head and the second endmost liquid ejecting head is disposed at a position deviated toward the remaining one of the first endmost liquid ejecting head and the second endmost liquid ejecting head.
