THIN FILM TRANSISTOR ARRAY SUBSTRATE FOR DIGITAL X-RAY DETECTOR DEVICE AND DIGITAL X-RAY DETECTOR DEVICE INCLUDING THE SAME

Abstract:

A thin film transistor array substrate for a digital X-ray detector device includes a p+ type semiconductor layer and a p- type semiconductor layer having different impurity concentrations are disposed above an intrinsic semiconductor layer of the PIN diode and an n+ type semiconductor layer and an n- type semiconductor layer having different impurity concentrations are disposed below the intrinsic semiconductor layer of the PIN diode to minimize ejection of holes by the p- type semiconductor layer and minimize ejection of electros by the n- type semiconductor layer, thereby minimizing occurrence of leakage current of the PIN diode.
