Abstract
An optical writing device includes a substrate, an array of pixel electrodes, each of which is provided with a luminescent material, a filament electrode disposed in parallel with the array, an enclosure member for enclosing the pixel and filament electrodes and the array, and driver I.C. chips mounted on the substrate. Such a structure may be made extremely compact in size with low cost.
