PURPOSE: A light emitting device, a light emitting device package, and a light unit are provided to improve white light extraction efficiency. CONSTITUTION: A first light emitting structure(10) includes a first conductive type first semiconductor layer(11), a first active layer(12), and a second conductive type second semiconductor layer(13). A first reflection electrode is electrically connected to the second conductive type second semiconductor layer. A second light emitting structure(20) includes a first conductive type third semiconductor layer(21), a second active layer(22), and a second conductive type fourth semiconductor layer(23). A second reflection electrode(27) is electrically connected to the second conductive type fourth semiconductor layer. A contact part(45) is electrically connected to the first conductive type first semiconductor layer and the second reflection electrode. A first insulation layer(41) is arranged on the upper and lateral sides of the second light emitting structure. |
