Light emitting device using light emitting diode

Abstract:

A light emitting device comprises an emission area and a non-emission area defined at a substrate, wherein the non-emission area includes a first non-emission area and a second non-emission area where a first pad and a second pad are respectively disposed; a light emitting diode disposed over the substrate and including a first electrode, an emission layer and a second electrode; an auxiliary electrode directly contacting the first electrode; a buffer layer disposed between the substrate and the light emitting diode; and a light extraction layer disposed between the buffer layer and the substrate, wherein the first electrode includes a contact portion directly contacting the auxiliary electrode, an electrode portion disposed in the emission area and a short-circuit-preventing portion disposed between the contact portion and the electrode portion.
