Abstract
Provided herein is a digital x-ray detector and a method for repairing a bad pixel thereof, the detector including a substrate; a gate line and a data line formed on the substrate such that the gate line and the data line intersect each other to form a pixel domain; a thin film transistor formed within the pixel domain such that the thin film transistor is adjacent to a portion where the gate line and the data line intersect each other, the thin film transistor including a gate electrode, an active layer, a source electrode and a drain electrode; a PIN diode which is formed within the pixel domain and which includes a lower electrode connected to the source electrode of the thin film transistor, a PIN layer formed on the lower electrode, and an upper electrode formed on the PIN layer; a bias line connected to the upper electrode of the PIN diode; and a scintillator arranged above the PIN diode, wherein on at least one of a surface of the drain electrode which faces the PIN diode and a surface of the PIN diode which faces the drain electrode, a groove is formed such that it expands a distance between the drain electrode and the PIN diode.
