Abstract
A light emitting device package includes a cell array having a first surface and a second surface located opposite to the first surface and including, on a portion of a horizontal extension line of the first surface, semiconductor light emitting units each including a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer sequentially located on a layer surface including a sidewall of the first conductivity type semiconductor layer; wavelength converting units corresponding respectively to the semiconductor light emitting units and each arranged corresponding to the first conductivity type semiconductor layer; a barrier structure arranged between the wavelength converting units corresponding to the cell array; and switching units arranged in the barrier structure and electrically connected to the semiconductor light emitting units.
