Abstract: PURPOSE:To enhance a reduction in electron orbit deflection by providing a deflection correcting anode electrode between a screen electrode and an anode electrode. CONSTITUTION:The electrons generated from the photoelectric surface of an input surface 2 according to the input of a subject image signal are focused and accelerated by focusing electrodes 41-43 and an anode electrode 51, and taken out from a screen electrode 3. A deflection correcting anode electrode 52 having nearly the same inclined surface as an electron orbit surface to which a potential lower than that to the electrode 51 is added is also provided between the electrodes 51 and 3. According to this simple constitution, an electron orbit deflection which is exponentially increased as it is closer to the periphery can be remarkably suppressed, and the whole deflection is reduced.
