<p><P>PROBLEM TO BE SOLVED: To realize low power consumption of an image display device comprising a display panel provided with an image memory element in a pixel. <P>SOLUTION: An image electrode 25 of a liquid crystal element 5 is connected to a non-volatile image memory element 1 of which the resistance value is changed over by phase change. An output of a thin film transistor 17 driven by a scanning electrode line 7 and a signal electrode line 9 is connected to the image electrode 25. When the scanning electrode line 7 is selected to bring the voltage into the high level, the thin film transistor 17 is turned on, and a current signal flowing to the signal electrode 9 at this timing is made to flow to the reference electrode line 15 through the image memory element 1. The resistance of the image memory element 1 varies according to the current value or pulse width flowing through the image memory element 1, and is stored as a resistance value. A liquid crystal driving voltage applied to the liquid crystal 5 varies according to the resistance of the image memory element 1, and makes the liquid crystal element perform displaying. <P>COPYRIGHT: (C)2004,JPO</p> |
