PROBLEM TO BE SOLVED: To change a display image without having to perform rewriting.SOLUTION: A display section 3 includes digital memory elements 618a-618d holding the potential to specify a display image, and liquid crystal cells 614a-614d displaying by supplying the potential held by the digital memory elements 618a-618d. Since the display section 3 also includes a switching line 6, a branch line 7, a digital memory element 621, and AND circuits 622a-622d for controlling so that, of the pixels constituting the display section 3, the pixels belonging to a display pixel group supply the potential from digital memory elements 618a and 618d to the liquid crystal cells 614a and 614d so as to display an image on the display section 3, and the pixels, belonging to a non-display pixel group that does not supply the potential from the digital memory elements 618b and 618c to the liquid crystal cells 614b and 614c so as not to display an image on the display section 3, display image can be changed having to rewrite. |
