Patent ID: 7456568

Claim:
An active matrix type organic electroluminescent device, comprising: a plurality of pixels disposed on a substrate; a first passivation layer disposed in the pixels and being made of SiO 2 ; and a second passivation layer disposed in the pixels and being made of SiNx; wherein a pixel comprises: a driving area where a first thin film transistor driven by a driving circuit and a second thin film transistor driven by the first thin film transistor are disposed; and a light-emitting area where a display unit driven by the second thin film transistor is disposed, wherein the light emitting area comprises: a first pixel electrode disposed over the substrate and coupled to the second thin film transistor; a second pixel electrode disposed over the first pixel electrode; and a light-emitting layer interposed between the first pixel electrode and the second pixel electrode, wherein at least a portion of the second passivation layer corresponding to the light emitting area is patterned to be eliminated so that the first pixel electrode and each layer disposed below the first pixel electrode in the light emitting area has a refractive index in a range of 1.4 to 1.6, and wherein the first passivation layer covers the second passivation layer and the first pixel electrode is formed on the first passivation layer.
