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.

Abstract: A semiconductor light-emitting device includes a light-emitting pixel region and a pad region, and includes light-emitting structures, a partition wall structure, a passivation structure, and a fluorescent layer, positioned in the light-emitting pixel region, and a pad unit positioned in the pad region. The partition wall structure includes partition walls defining pixel spaces. The passivation structure surrounds the partition walls and includes a first passivation layer including a first insulating material and a second passivation layer including a second insulating material different from the first insulating material. The passivation structure includes a first portion on a top surface of the partition walls, a second portion on a sidewall of the partition walls, and a third portion between the light-emitting structures and the fluorescent layer. A first thickness of the first portion is less than or equal to a second thickness of the second portion.
