Abstract: An electron gun assembly of a cathode ray tube has a main electron lens section comprising at least four electrodes, provided in a sequence of first, second, third and fourth grids, a middle first voltage is applied to the first grid, and an anode voltage is applied to the fourth grid. The adjacent second grid and third grid are connected by a resistor, and second and third voltages of substantially the same potential, corresponding to voltages higher than the middle first voltage and lower than the anode voltage, are applied thereto. An asymmetrical lens is provided between the adjacent second grid and the third grid second lens region, and a voltage which changes in synchronism with the deflecting magnetic field is applied to the first grid. Therefore, it is possible to provide a cathode ray tube wherein a phenomenon of sideways deviation of an electron beam at the peripheral region of a screen caused by lens magnification difference in the horizontal and vertical directions is reduced, and which has good image characteristics in all regions of the screen.
