PURPOSE: To provide an electrode structure of a constitution which can be manufactured at a low cost with good yield and which permits precise location and fixation of a plurality of electrodes; and to provide an image display device which is free from electric discharging between the electrodes constituting the display device and also deformation of the electrodes.

CONSTITUTION: A plurality of electrodes used for converging, deflecting, and controlling an electron beam are located in place and fixed on one plane in parallel with a screen in a proper distribution, and thereby an electrode structure for an image display device is formed, wherein electrodes 2, 3, etc., are secured by a plurality of porous glass blocks 5 fixed to a coupling plate 4.
