Abstract:
An active matrix organic electroluminescence display device comprising:a scan line in one direction; a data line substantially perpendicular to the scan line; a power line substantially parallel to the data line, keeping a distance with the data line; an electroluminescence device emitting light in a pixel region among the scan line, the data line and the power line; a switching transistor for switching a signal of the data line according to a signal of the scan line, the switching transistor including a channel region made of polycrystalline silicon having a longitudinal grain, wherein the longitudinal grain is substantially parallel to a current flow direction in the channel region; and a driving transistor for applying a power supply of the power line to the electroluminescence device according to a signal applied through the switching transistor.
