ABSTRACT:
A photoelectric conversion device is disclosed which comprises a large number of photoelectric conversion elements arranged in an array on a substrate and thin film transistors individually corresponding to the photoelectric conversion elements and arranged in an array in parallel with the direction of the array of the photoelectric conversion elements, in which two electrodes of each of the thin film transistors are arranged to oppose each other in the direction of the array of the photoelectric conversion elements so that the width of the channel formed between both the electrodes may be prolonged, and thereby, switching operation by the thin film transistor is made reliable and the manufacture of the thin film transistor portion is facilitated.
