Abstract
An image displaying apparatus having a first plate including at least an electron beam source, and a second plate including an anode to which an electric potential for accelerating an electron beam from the electron beam source is applied, and a potential regulating electrode to which a predetermined electric potential lower than that of the anode is applied. The potential regulating electrode is situated at an outside of the anode. A spacing member is provided between the first and second plates, and contacts both of the anode and the potential regulating electrode. The spacing member includes an electrode contacting or being disposed close to the potential regulating electrode thereby being electrically connected with the potential regulating electrode. The electrode included in the spacing member contacts or is disposed close to an electrode included in the first plate, thereby electrically connecting with the electrode included in the first plate.
