ABSTRACT:
An image display system for display image information obtained by accessing an image data base or the like which was stored in an electronic filing device. The system has: an electronic filing device to store a plurality of pieces of information; a plurality of terminal devices; a common image information memory such as a video RAM to store the image information read out of the electronic filing device on the basis of an instruction from at least one of the terminal devices; and a distributor to distribute and transfer the image information stored in the VRAM to any or all of the terminal devices in accordance with an image transfer instruction from such terminal device(s). A ferroelectric liquid crystal or other display panel which can hold the image information for a predetermined time may be used as a display. The display information can be individually effectively accessed from the electronic filing device by each terminal device while commonly using a single VRAM.
