PURPOSE: To clearly identify painted out graphics by painting out roughly dots constituting a symbol mark against painting out densely dots constituting painting out graphic.

CONSTITUTION: Each constituting dot 7 for painting out graphics constitutes a dot pattern formed of display dots 1a and non-display dots 1b which are alternately arranged in both vertical and horizontal directions and all of the dots 8 used for painting out symbol marks 6 are display dots. Thus the constituent dots used for painting out the symbol marks 6 are arranged denser than those 7 used for painting out graphics. Therefore, even when a painted-out symbol mark and painted-out graphic are superimposed the part where the painted-out symbol mark and painted-out graphic are superimposed can be identified clearly from the other part where the symbol mark and graphic are not superimposed upon another, since the dots used for painting out the symbol mark appear without fail in the areas of the non-display dots of the graphic.
