Abstract
A color 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, in which the 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 the potential Vm which is higher than the focusing voltage (Vf) and lower than the anode voltage (Va), and the focusing electrode (15). These voltages are set by a dividing resistor (30).
