LIGHT EMITTING DIODE DEVICE COMPRISING A DIFFUSION BARRIER LAYER AND METHOD FOR PREPARATION THEREOF

摘要

Disclosed is a light emitting diode device in which (a) a substrate; (b) a binder layer; (c) an ohmic contact metal layer; and (d) a light emitting diode section are stacked in sequence, wherein the light emitting diode device has an electrically conductive layer for preventing components of the binder layer from diffusing into the ohmic contact metal layer, and being formed between the ohmic contact metal layer and the binder layer. In such a light emitting diode device, the electrically conductive layer capable of preventing the binder layer components from diffusing into the ohmic contact metal layer is formed between the ohmic contact metal layer and the binder layer, so stability and product qualities of the light emitting diode device can be improved.
