Abstract
A thin film transistor array substrate for a digital photo-detector is provided. The photo-detector 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; a thin film transistor at each intersection between the gate lines and the data lines to output a photoelectric conversion signal from the photodiode to the data lines in response to a scan signal supplied by the gate lines; and a light-shielding layer over each channel region of the respective thin film transistors. Each light-shielding layer is electrically connected to the respective gate line.
