An active matrix organic electroluminescence device includes a substrate, a gate
line on the substrate, a data line crossing the gate line, a power line parallel
with the gate line, a switching thin film transistor electrically connected to
the gate line and the data line, wherein the switching thin film transistor includes
a first gate electrode, a first active layer, and first source and drain electrodes,
a driving thin film transistor electrically connected to the first drain electrode,
wherein the driving thin film transistor includes a second gate electrode, a second
active layer, and second source and drain electrodes, and a luminescent diode connected
to the driving thin film transistor and the power line.
