Patent ID: 7239077

Claim:
An image display device comprising: a face substrate having an anode and phosphors on an inner surface thereof; a back substrate having first electrode lines which extend in one direction and are arranged in parallel in another direction which intersects one direction, and second electrode lines which are arranged in a non-contact manner with the first electrode lines, extend in another direction and are arranged in parallel in one direction on an inner surface thereof, the back substrate being arranged to face the face substrate in an opposed manner with a given distance therebetween; a sealing frame body which is inserted between the face substrate and the back substrate in a state the sealing frame body surrounds a display region and holds the given distance; wherein electron beams are pulled out by imparting the potential difference between the first electrode lines and the second electrode lines and the electron beams are allowed to impinge on the phosphors of the face substrate thus performing an image display; wherein the image display device includes a surge current absorbing electrode which is arranged between the face substrate and the back substrate and has apertures which allow the electron beams to pass therethrough; wherein a DC bias power source and a high voltage absorbing means are connected in parallel between the surge current absorbing electrode and a ground surface; and wherein a conductive spacer is interposed between the anode and the surge current absorbing electrode.
