Abstract
PURPOSE: To enable to modulate each electron beam with deflection toward horizontal direction, by taking special shape for the third grid, in the cathode ray tube unit having electron gun in which a plurality of electron beams are arranged in- line.
CONSTITUTION: When the length of the tube parts 5R, 5G and 5B of the electrode G3b of the third grid G3 is selected almost equal to or greater than the diameter, the invasion of high voltage from the fourth grid G4 is caused almost in the tubes and no high voltage invasion is almost caused to the grid G4 between the ends 4a and 4b of the both electrodes. Since the end surfaces 4a and 4b are orthogonal to the arrangement direction of the electron beams 1R, 1G and 1B and selected so that they intersect the core center O with an angle, electrostatic field caused between the both ends is formed with the one of the components relating to the direction of each beam scanning and each beam is subject to the deflection of horizontal direction.
