A double-faced field emission display device includes two parallel fluorescent screens ( 10, 10 ') and an electron emission structure ( 20 ) located between the fluorescent screens. Each fluorescent screen includes a transparent substrate ( 21, 21 ') with an anode plate ( 12, 12 ') and coplanar fluorescent layers ( 13, 13 ') formed at an inner surface of the transparent substrate. The electron emission structure includes an opaque insulative substrate ( 28 ) with cathode plates ( 26, 26 '), electron emitters ( 27, 27 ') and grid plates ( 25, 25 ') formed at each of opposite surfaces ( 281, 282 ) thereof. Symmetrically opposite pairs of same electrodes are electrically interconnected so that the fluorescent screens can simultaneous display a same image. Only a single driving system is needed to achieve the simultaneous display.
