    Abstract: A light emitting package is provided to include a substrate on which a circuit pattern is formed, a first optic layer, a light controller, and a second optic layer. The first optic layer may be arranged on the substrate to be electrically connected to the circuit pattern and generate and emit light. The light controller may cover a side surface of the first optic layer and may reflect light emitted from the side surface of the first optic layer. In addition, the second optic layer may cover the first optic layer and the light controller and be disposed on the substrate. The second optic layer may include a securing region secured on the substrate and a light emitting region disposed over the securing region. Light emitted from the first optic layer may be emitted to the outside of the second optic layer through the second optic layer.
