ABSTRACT:
To propose 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 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 the 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), the anode electrode (17) and the intermediate electrode (16) are respectively formed of cylindrical bodies each having an ellipse cross-section and closed by the electric field correcting electrode plates (25, 26, 27, 28) having three electron beam penetrating portions bored therethrough so as to be arrayed in an in-line fashion.
