Display unit with reduced leakage magnetic field

Abstract

A display unit that enables reduction in number of additional parts, decrease in leakage magnetic field in a VLF band generated from the display unit in all directions at low cost, and suppression of the leakage magnetic field to the specified value or less according to MPR-II Standard with tolerance is provided. The display unit comprises a cathode-ray tube having a neck portion, a deflection yoke 2 that is mounted at a predetermined position on a periphery of the neck portion, and a driving circuit 3 that has a coil 4 and drives the deflection yoke 2. The driving circuit 3 (the coil 4) is provided at such a position and in such a direction that a magnetic field E.sub.2 generated from the driving circuit 3 (the coil 4) cancels out a leakage magnetic field generated E.sub.1 from the deflection yoke 2 substantially at the position in front of and 50 cm away from the center of a face panel of the cathode-ray tube.
