Abstract
Field-emitted electrons are converged by a structure according to the present invention in which odd order gate lines are connected to a first gate lead electrode, while even order gate lines are connected to a second gate lead electrode. When the first gate lead electrode is selected and operated, the potential of the second gate lead electrode is made to be a low level. Since the odd order gate line is disposed between low level even order gate lines, emitted electrons can be converged. When the second gate lead electrode is selected and operated, a contrary process is performed so that emitted electrons are converged. Each gate line has three dot-like field emission arrays, which correspond to red, green and blue color components, so that color image apparatus is structured.
