Abstract
A light emitting device includes a first light emitting cell, a second light emitting cell, a first conductive pattern, a second conductive pattern, and a connection pattern. The connection pattern includes contact portions electrically connected to a second conductivity type semiconductor layer of the first light emitting cell and a first conductivity type semiconductor layer of the second light emitting cell. At an edge of a first region facing the second light emitting cell, one contact portion of the first conductive pattern is disposed between the contact portions of the connection pattern electrically connected to the second conductivity type semiconductor layer of the first light emitting cell, and one contact portion of the first conductive pattern is open outwards.
