<p>An electron gun for a colour cathode-ray tube which increases the degree of freedom in designing its main electron lens, decreases the electron beam spot diameter, and achieves high resolution, is proposed, in which between the focusing electrode (15) applied with the focusing voltage (Vf) and the anode electrode (17) applied with the anode voltage (Va), there is provided an intermediate electrode (16) applied with a potential Vm which is higher than the focusing voltage (Vf) and lower than the anode voltage (Va). Additionally, a deviding resistor (30) having a first terminal (t1) connected to said anode electrode (17), a second terminal connected to said focusing electrode (15), and a third terminal (t3) provided between said first terminal and said second terminal connected to said intermediate electrode (16) is incorporated in the electron gun structure. <IMAGE></p> |
