ABSTRACT:
Using a cathode material with which an electron emission having sufficient intensity is obtained with a low electric field, over a back substrate, cathodes and first control electrodes are formed on the same plane, which is parallel to the back substrate, thus forming electron beam sources, and second control electrodes, which focus electrons taken out from the electron beam sources, are formed, whereby it is possible to obtain an image display of high brightness.
