Abstract:
1. An X-ray detector, comprising: a thin film transistor substrate, which comprises a substrate, a plurality of data lines and a plurality of gate lines intersected to define a plurality of pixel regions, wherein each of the pixel regions comprises at least one thin film transistor, and the thin film transistor comprises: a photo-diode array layer, having plurality of photo-diodes electrically connected to the corresponding thin film transistor; wherein the source electrode is electrically connected to the semiconductor layer through a first conductive via hole having a first base portion at the semiconductor layer, the drain electrode is electrically connected to the semiconductor layer through a second conductive via hole having a second base portion at the semiconductor layer, and at least one of projection areas of the first base portion and the second base portion vertically projected on the substrate has a non-overlapping region beyond a projection area of the gate electrode vertically projected on the substrate.
