Patent ID: 7615922

Claim:
An electro-luminescent display device, comprising: a substrate comprising a first region and a second region; a thin film transistor disposed on the first region of the substrate and comprising a pair of source/drain electrodes; an interlayer insulator disposed on the second region of the substrate and covering the thin film transistor; an opaque electrode overlying the interlayer insulator and electrically connected to the thin film transistor, wherein one of the pair of source/drain electrodes of the thin film transistor directly contacts the opaque electrode and the other is directly below the opaque electrode; an opaque layer, overlying the opaque electrode, having a first opening exposing a portion of the underlying opaque electrode, wherein the opaque electrode is extended across the entire bottom of the opaque layer; an electro-luminescent medium layer disposed over the exposed portion of the opaque electrode and apart from the sidewall surface of the first opening and non-contacted with the sidewall surface of the first opening, wherein the top surface of the electro-luminescent medium layer is substantially below the top surface of the opaque layer; and a transparent electrode disposed on the opaque layer and directly on the exposed sidewall surface of the first opening and the top surface of the electro-luminescent medium layer.
