Integrated input-output device having a reading and a printing section on a single substrate

An integrated input-output device having a reading and a printing section on a single substrate comprising:

• a first transparent substrate;
• a photoelectric converting region formed over one side portion of said first transparent substrate and adapted to convert an optical signal into an electrical signal and generate a photoelectric charge;
• a first switching circuit formed over a portion of the first transparent substrate in one side of said photoelectric converting region and adapted to selectively output said photoelectric charge from the photoelectric converting region;
• a second switching circuit formed over a portion of the first transparent substrate in one side of said first switching circuit and adapted to switch data values, said second switching circuit having a source/drain electrode in common with the first switching circuit;
• a liquid crystal shutter formed over a portion of the first transparent substrate in one side of said second switching circuit and adapted to output electrical data from the second switching circuit in the form of an optical signal;
• a second transparent substrate bonded to the first transparent substrate to define a space therebetween;
• a black matrix formed over said second transparent substrate except for a region corresponding to said liquid crystal shutter and adapted to shield a light beam;
• a transparent electrode formed over both the black matrix and the second transparent substrate;
• and
• a liquid crystal layer disposed in said space and adapted to permit a light beam to pass therethrough or shield the light beam.
