Abstract
An image display apparatus includes a plurality of line cathodes arranged horizontally in parallel with each other; an electron beam leading electrode device allowing a plurality of electron beams radiated from the line cathodes to pass therethrough; a signal electrode device for controlling quantity of the electron beams passing therethrough according to a video signal; a focusing electrode device for focusing the electron beams; a horizontal deflecting eletrode device for electrostatically deflecting the electron beams horizontally; a vertical deflecting electrode device, for electrostatically deflcting the electron beams vertically, comprising of a pair of comblike conductive plates each having vertical teeth spaced to intervals, opposed to each other, and alternating with each other in the same plane, electron beams which pass through the vertical deflecting electrode device crossing over in a vertical section thereof and being focused; and a display device which emits a light as a result of a collison of electron beams.
