PURPOSE:To obtain an excellent image quality being equal to a TFT of a three-terminal element, and also, to simplify the structure by radiating light beams to a photoconductive body between a transparent picture element electrode and a common electrode or a signal electrode. CONSTITUTION:Between glass substrates 9, 10 to which polarizing films 11, 12 have been stuck, a liquid crystal 6, a data signal use electrode 7, a common electrode 5, a transparent picture element electrode 4, an oriented film and a color filter 13 are provided. Also, an amorphous Si thin film is provided as a photoconductive body 3 between the electrodes 4, 5. In this state, when a scanning signal of light is led to an optical waveguide 2, a part thereof irradiates the photoconductive body 3 through the electrode 4, a resistance value is lowered quickly by a generated and a carrier, the electrodes 4, 5 become a conducting state, an applied voltage to the electrode 7 in this case is applied to the liquid crystal 6, charge is accumulated in a capacitor consisting of the electrodes 7, 4, and an image memory can be formed. |
