PURPOSE: A light emitting device is provided to improve uniformity of illuminance by arranging a plurality of light emitting elements with a zigzag shape. CONSTITUTION: A light emitting device(100) includes a first light emitting unit(200), a second light emitting unit(300), and an optical unit(400). The first light emitting unit includes a plurality of first light emitting devices. A plurality of first light emitting elements are arranged along a first direction with a first interval. A second light emitting unit includes a plurality of second light emitting elements. The plurality of second light emitting elements are arranged along the first direction with the first interval. At least one second light emitting element is positioned between the first light emitting elements. The optical unit controls the path of the light emitted from the second light emitting element and includes one of transparent glass, quartz and plastic.
