PURPOSE: A light emitting device and a lighting system including the same are provided to uniformly emit light to all region of an upper side by transmitting light from an active layer to the rear of a metal filter according to a diffraction principle. CONSTITUTION: A junction layer(150), a reflection layer(140) and an ohmic layer(130) are successively formed on a conductive support substrate. The junction layer is combined with the reflection layer and the conductive support substrate. A light emitting structure(120) is formed on the ohmic layer. The light emitting structure includes a first conductive semiconductor layer(122), an active layer(124), and a second conductive semiconductor layer(126). A transparent conductive layer(170) is formed on the light emitting structure. A metal filter(180) is patterned on the transparent conductive layer. |
