Drive circuit for image display device

A drive circuit for an image display device, wherein said image display device comprises:

• a first substrate;
• a plurality of cathode electrodes formed on said first substrate in a stripe-like manner and including emitters for field-emitting electrons;
• cathode lead-out electrodes led out of said cathode electrodes, respectively;
• a plurality stripe-like gate electrodes laminatedly formed on said cathode electrodes in a manner to be perpendicular to said cathode electrodes while being insulated from said cathode electrodes;
• gate lead-out electrodes led out of said gate electrodes, respectively;
• a second substrate arranged so as to be spaced at a predetermined distance from said first substrate;
• a plurality of stripe-like anode electrodes arranged in parallel to said gate electrodes and opposite to said gate electrode in positional relationship of 1:1;
• phosphors arranged on said anode electrodes in turn to display a color image;
• and
• a first anode lead-out electrode connected to said anode electrodes at every second interval and a second anode lead-out electrode connected to the remaining part of said anode electrodes;
• said first and second anode lead-out electrodes being alternately driven;
• only a part of said gate electrodes arranged opposite to said anode electrodes driven being driven;
• a part of said gate electrodes adjacent to said gate electrodes driven being kept at a low level.
