Patent ID: 7122954

Claim:
An organic electroluminescent (EL) device having plurality of scanning lines, a plurality of signal lines extending in the direction crossing the plurality of scanning lines, a plurality of common feeders, and pixels that are provided in intersections of the scanning lines and the signal lines, each pixel having a switching thin film transistor, a current thin film transistor where an image signal is supplied to a gate from the signal line, a first electrode where a driving current is supplied from the common feeders when being connected electrically to the common feeders through the current thin film transistor, and a light-emitting part interposed between the first electrode and the second electrode are provided, comprising: a concave part formed in a material layer provided on a substrate; and a power connection part formed in the concave part, the power connection part comprising the plurality of scanning lines, the plurality of signal lines, the plurality of common feeders, the switching thin film transistors, and the current thin film transistors, the first electrode and the light-emitting part formed above at least part of the power connection part.
