Abstract

PURPOSE:To obtain an image having presence by executing successively storage until all images are fetched once by a storage capacitor for executing temporary storage in a display part and a first switch group for fetching image data, and displaying them simultaneously. CONSTITUTION:A transistor 12 for showing a first switch group is switched through a line 15, whenever a vertical scanning signal of a vertical scanning circuit 18 is generated, through a line 16 as to image data of a horizontal data holding circuit 19, and it is stored successively in a storage capacitor 13 containing the parasitic capacity, as well. A transistor 14 for showing a second switch group transfers the image data to a unit display element 11 from the storage capacitor 13, and its gate electrodes are all connected in a lump and switched simultaneously by a simultaneous pulse of a simultaneous pulse circuit 20. Accordingly, the image data taken instantaneously is fetched in order of sending an image, but it is accumulated once and whole image can be changed simultaneously. In such a way, a forceful image can be displayed.
