Patent ID: 8803210

Claim:
An X-ray detector, comprising: a substrate; a gate line that is extended in a first direction on the substrate; a gate electrode that is extended from the gate line; a semiconductor layer that is positioned on the gate electrode; a source electrode and a drain electrode that are positioned on the semiconductor layer; a lower electrode that is extended from the drain electrode; a photodiode that is positioned on the lower electrode; a first insulation layer that is positioned on the source electrode and the drain electrode and that comprises a first opening that exposes the source electrode; a data line that is extended in a second direction intersecting the first direction on the first insulation layer to intersect the gate line with the first insulation layer interposed between the data line and the gate line, and the data line being electrically connected to the source electrode through the first opening; and a connection that is positioned between the data line and the source electrode to correspond to the first opening and that electrically connects the data line and the source electrode, the connection having a flange overlapping the first insulation layer and overlapping a contiguous portion of the data line.
