<P>PROBLEM TO BE SOLVED: To reduce power consumption of an image display device, composed of a display panel provided with an image memory element within a pixel. <P>SOLUTION: The non-volatile image memory element 1, the resistance value of which is changed by a phase transition, is connected to a pixel electrode 25 of a liquid crystal element 5. The output of a thin-film transistor 17, driven by a scanning electrode line 7 and a signal electrode line 9, is connected to the pixel electrode 25. When the scanning electrode line 7 is selected and a voltage rises to a high level, the thin-film transistor 17 is turned on, and a current signal flowing to the signal electrode 9 with this timing flows through the image memory element 1 to a reference electrode line 15. The resistance of the image memory element 1 changes, according to the current value or pulse width flowing through the image memory element 1 and is stored as the resistance value. The liquid crystal drive voltage, applied to the liquid crystal element 5 according to the resistance of the image memory element 1, changes, and display is performed on the liquid crystal element 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
