THIN FILM TRANSISTOR, THIN FILM TRANSISTOR ARRAY PANEL INCLUDING THE SAME AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a thin film transistor, a thin film transistor display panel including the same, and a manufacturing method thereof. The thin film transistor according to one embodiment of the present invention comprises a gate electrode; a gate insulating film which is located the above or below the gate electrode; a channel region which overlaps with the gate electrode while placing the gate insulating film therebetween; and a source region and a drain region which are located in the same layer as the channel region, are connected to the channel region and face to each other on the basis of the channel region, wherein the channel region, the source region, and the drain region include an oxide semiconductor, and wherein the carrier concentration of the source region and the drain region is larger than the carrier concentration of the channel region.
