Thin film transistor array substrate for digital photo-detector

摘要

A thin film transistor array substrate for a digital photo-detector is provided. The thin film transistor array substrate includes a plurality of gate lines to supply a scan signal; a plurality of data lines to output data, the data lines arranged in a direction crossing the gate lines, wherein cell regions are defined by the gate lines and the data lines; a photodiode in each of the cell regions to perform photoelectric conversion; and a thin film transistor at each intersection between the gate lines and the data lines to turn on according to the scan signal of the gate lines and output the photoelectric conversion signal from the photodiode to the data lines. A contact area between a source electrode of the thin film transistor and a first electrode of the photodiode is at a portion outside an area covered by a photodiode region.
