1. A light emitting device, comprising:
a substrate;
a plurality of light emitting cells arranged on the substrate to be spaced apart from each other; and
a connection wire configured to electrically connect the plurality of lighting cells which are disposed adjacent to each other,
wherein one of the plurality of light emitting cells comprises a plurality of first segments, and another one of the plurality of light emitting cells comprises a plurality of second segments respectively facing the first segments,
wherein the first segments comprise:
a 1-1 segment having an end plane contacting the connection wire; and
at least two 1-2 segments extending from both sides of the 1-1 segment, each of the at least two 1-2 segments having an end plane that does not contact the connection wire, and
the second segments comprise:
a 2-1 segment having an end plane contacting the connection wire and facing the 1-1 segment; and
at least two 2-2 segments extending from both sides of the 2-1 segment, each of the at least two 2-2 segments having an end plane that does not contact the connection wire, and facing the 1-2 segment,
wherein a first separation distance between the 1-1 segment and the 2-1 segment facing each other is greater than a second separation distance between the 1-2 segment and the 2-2 segment,
wherein each of the end planes of the 1-2 segments facing the 2-2 segments protrudes more than the end plane of the 1-1 segment facing the 2-1 segment by a first protrusion length,
wherein each of the end planes of the 2-2 segments facing the 1-2 segments protrudes more than the end plane of the 2-1 segment facing the 1-1 segment by a second protrusion length, and
wherein the first protrusion length and the second protrusion length are identical.
