摘要：
In an image display apparatus, horizontal-extended line cathodes (22a--22d), an electron beam extraction electrode (23), a control electrode (24), a first focusing electrode (25) having horizontal-elongated apertures (35) , a second focusing electrode (26) having vertical-elongated apertures (36) , a horizontal deflection electrode (27a, 27b), a vertical deflection electrode (28a, 28b) and a screen (29) are provided in this order toward a travelling direction of electron beam, and each of both deflection electrodes comprises a pair of comb-shaped conductive sheets which are insulatedly interdigitated with each other on the same vertical plane.
