Claim Text:
1. An organic light emitting display device comprising: a driving transistor including a first oxide semiconductor region having at least a channel area, and the driving transistor for driving an organic light emitting diode; a first transistor including a second oxide semiconductor region having at least a channel area, the first transistor controlled by a scan signal, and connected between a reference voltage line and a first node of the driving transistor; a second transistor including a third oxide semiconductor region having at least a channel area, the second transistor controlled by the scan signal commonly provided from a gate line, and connected between a data line and a second node of the driving transistor; a first plate including a fourth oxide semiconductor region connected to the first oxide semiconductor region of the driving transistor and the second oxide semiconductor region of the first transistor, the fourth oxide semiconductor region of the first plate in a same semiconductor layer as the first oxide semiconductor region of the driving transistor and the second oxide semiconductor region of the first transistor; a second plate positioned on the first plate, and connected to the third oxide semiconductor region of the second transistor and a gate electrode of the driving transistor; and a pixel electrode of the organic light emitting diode, positioned on the second plate and connected to the first plate through a contact hole.
