Thin film transistor array substrate for an x-ray detector and method of fabricating the same

A method of fabricating a thin film transistor (TFT) array substrate for an X-ray detector, the method comprising:

• providing a substrate;
• forming a gate line and a gate electrode on the substrate;
• forming a data line crossing the gate line, a source electrode, and a drain electrode on the substrate;
• forming a first electrode on the substrate to be connected to the drain electrode;
• forming a passivation layer over the gate line, the data line, the source electrode, the drain electrode, and the first electrode;
• forming a first contact hole on the passivation layer;
• forming a photoconductor over the passivation layer and the first electrode exposed by the first contact hole;
• and
• forming a second electrode on the photoconductor.
