Abstract
The object of the present invention is to provide an image display device capable of radiating over an image formed into a character with a uniform luminosity as a luminescent surface made according to the dot matrix system without increasing the number of components. To this end, the display device includes the first luminescent section having a prescribed area and the second luminescent section constituting a display with an area larger than that of the first luminescent section, wherein the first and the second luminescent sections include luminescent bodies radiating as electrons move and a pair of electrodes sandwiching these luminescent bodies, at least one of these electrodes determines the luminescent area thereof, and the second luminescent section is constituted by a plurality of divided electrodes.
