摘要： flat cathode ray tube in which first and second electrodes (2), (3) are formed at positions within a flat tubular body (1) so that they face each other across the thickness to form a first deflection system, a fluorescent surface (4) is formed on the first electrode (2) side, and a second deflection system (6) for electromagnetic deflection is provided between the first deflection system and an electron gun (5). A third electrode (10) which surrounds the region of the second deflection system (6) to sufficiently cover it is formed integrally with the second electrode (3), and a voltage lower than that of the first electrode (2) is supplied to the second and the third electrodes (3), (10). This cathode ray tube can reduce power consumption and suppress circular-arc distortion.
