PURPOSE:To obtain a small sized picture element less in power consumption, by applying a voltage between an electrode adapted closely at the back of a semiconductor laminated substrate and a semiconductor provided at the four corners of the surface, so that conductive points are formed on the semiconductor substrate and the image is converted into an electric signal. CONSTITUTION:A single electric value P type semiconductor is provided at the back of N type semiconductor 3 of a single electric value to constitute a semiconductor substrate A. Further, a P type semiconductor 2 is formed at the four corners on the surface of the N type semiconductor 3 and a minus voltage is fed. Further, an electrode 5 is closely adhered at the back of a P type semiconductor 4 and a plus voltage is applied. Further, a depression layer is formed between the semiconductors 2 and 3. Thus, the conduction point alpha formed at the center of the N type semiconductor 3 is moved with the control of a voltage applied to P type semiconductors 2a-2d and the image received is converted into an electric signal. |
