Abstract: An electrostatic deflection type cathode-ray tube wherein a mesh electrode is disposed between a phosphor screen and at least two electron guns juxtaposed with their axes inclined with respect to the axis of the tube, and wherein a post-accelerating electrode system for the formation of a divergent electron lens is provided by means of an internal conductive film deposited on the inner wall surface of the funnel portion of the bulb of the tube and the mesh electrode, whereby there is eliminated the inconvenience of any occurrence of geometry distortion of raster due to the inclined disposition of the electron guns with respect to the axis of said tube.
