Abstract:
1. A light emitting device comprising: a light emitting structure having a first conduction type semiconductor layer, an active layer, and a second conduction type semiconductor layer; an ohmic layer disposed below the light emitting structure; a transparent conductive layer disposed on the light emitting structure; a passivation layer disposed at a side surface of the light emitting structure extended to sides and a top side of the transparent conductive layer; and a metal filter having an irregular pattern disposed in the transparent conductive layer, the metal filter having metal stripes and openings between the metal stripes, wherein an upper portion of a side surface of the second conduction type semiconductor layer directly contacts the passivation layer, wherein a lower portion of the side surface of the second conduction type semiconductor layer is opened, wherein an outer width of the opened lower portion of the second conduction type semiconductor layer is smaller than a width of the passivation layer, and wherein a lower surface of the passivation layer is separated from an upper surface of the ohmic layer.
