  • an image display section which selectively transmits light, said image display section including;

    a first transparent substrate,a second transparent substrate which is opposite to said first transparent substrate,a liquid crystal portion which is sandwiched between said first transparent substrate and said second transparent substrate,a plurality of pixel electrodes disposed in a matrix form, said plurality of pixel electrodes being disposed on a surface of said first transparent substrate, whereby said plurality of pixel electrodes are positioned between said liquid crystal portion and said first transparent substrate,a counter electrode disposed on a surface of said second transparent substrate facing said plurality of pixel electrodes, andmeans for selectively applying voltage to at least desired one of said plurality of pixel electrodes; and

    an image input section having a photo-detective portion for converting part of said light which has been transmitted through said pixel electrodes of said image display section and reflected from an original surface to be imaged, into an electrical signal.
