    摘要: Provided are a light emitting device and a light emitting device package. The light emitting device includes a transparent substrate, a light emitting structure, and a first reflection layer. The light emitting structure includes a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer that are disposed on a top surface of the substrate. The first reflection layer is disposed on a bottom surface of the substrate. The bottom surface of the substrate has a surface roughness of about 1 nm to about 15 nm in root mean square (RMS) value.
