A field emission display device and a field emission type backlight device having a sealing structure for a vacuum exhaust are provided. The field emission display device is constructed with a cathode substrate and an anode substrate attached to each other and facing each other and a vacuum-exhausted panel space formed therebetween to generated a visual image. Also, the field emission display device is constructed with a sealing member disposed along edges of the cathode substrate and the anode substrate to seal the panel space. At least one inlet exposed to the panel space and an exhaust passage through which the inlet communicates with an outside of the field emission display device are formed in the sealing member. The field emission display device and the field emission type backlight device according to the present invention has a reduced number of manufacturing processes and is suitable for a compact, slim and lightweight design, and a large screen by having the sealing structure for the vacuum exhaust.
