Abstract

PURPOSE: To prevent chromatic nonuniformity by furnishing an electroconductive layer of high impedance conductive material along the side face of a glass inner wall from the screen surface.
CONSTITUTION: For each of the divisions on the picture field of a screen as divided in matrix form in vertical and horizontal direction, an electron beam is deflected in the horizontal and vertical directions and complexly displayed on the screen, and as a whole a TV image is displayed. In this image display device, an electroconductive layer 21 of a high impedance material is furnished along the side face of the inner wall of a glass vessel 9 from the screen 9a surface to which a high voltage is impressed. Thereby the peripheral areas of the picture field can have the same parallel potential as the central area, and generation of chromatic nonuniformity in the picture field be prevented.
