    Abstract: A light-emitting device includes a plurality of first light-emitting regions contiguously arranged in a first direction. Each of the first light-emitting regions includes at least one light-emitting cell. A plurality of second light-emitting regions are contiguously arranged in the first direction. Each of the second light-emitting regions includes at least one light-emitting cell. The plurality of second light-emitting regions are adjacent to the plurality of first light-emitting regions in a second direction that intersects the first direction. A first driver controller controls emission of the plurality of first light-emitting regions. Each of the first light-emitting regions has a greater dimension than each of the second light-emitting regions in the second direction. The first driver controller simultaneously turns on or off an entirety of each of the first light-emitting regions.
