Abstract
An image display apparatus includes an electron beam generating source for generating the electrons which travel in parallel with each other and an extraction electrode for extracting the electron beams from the generated electrons. A control electrode is also included for selectively controlling a second quantity of electrons in the electron beams which have passed through the extraction electrode and a horizontal deflection electrode for electrostatically deflecting the electron beams. A vertical deflection electrode is provided for deflecting the electron beams which have passed through the horizontal deflection electrode. The vertical deflection electrode has a first comb-shaped conductive sheet having first parallel members and a second comb-shaped conductive sheet having second parallel members. The first members and the second members are alternatively formed adjacent to each in the horizontal direction. Furthermore, the first comb-shaped conductive sheet and the second comb-shaped conductive sheet have notches formed at regular intervals. The horizontal deflection electrode and the vertical deflection electrode are insulated from each other.
