Manuscript reading device
 A manuscript reading device for reading a manuscript comprises a plurality of photodiodes for storing electric charges in parasitic capacitances thereof corresponding to lightness-and-darkness information on each minute area of a picture image on the manuscript by way of biasing said photodiodes to a predetermined state, and a plurality of thin film transistors connected in series to associated one of the photodiodes for transferring the electric charges stored in said parasitic capacitances to a corresponding wiring capacitance of a rear wiring group in response to the application of a predetermined voltage to gate electrodes thereof, the electric charges transferred and stored in said wiring capacitance being sequentially outputted as picture information corresponding to said picture image on the manuscript, wherein the thin film transistor comprises an n-type thin film transistor to a gate electrode of which a positive voltage is applied, and the photodiode is biased by a positive voltage.
