Patent ID: 7319445

Claim:
An active matrix type organic electroluminescence device having a plurality of sub-pixels disposed on a substrate, wherein: each of the sub-pixels comprises: a first thin film transistor driven by a driving circuit, a second thin film transistor driven by the first thin film transistor, and a display portion driven by the second thin film transistor; the display portion comprises: a first electrode to receive a first electric charge from the second thin film transistor, a second electrode to receive a second electric charge from a second electrode connecting terminal disposed outside of the sub-pixel, a light emitting layer interposed between the first electrode and the second electrode, and an electric charge transfer layer interposed between the light emitting layer and at least one of the first and the second electrodes, wherein the electric charge transfer layer and the second electrode are shared by at lest two sub-pixels; and the second electrode and the second electrode connecting terminal are directly electrically connected.
