2. Description of the Related Art The picture tube apparatus has become popular because the market has rapidly expanded due to the spread of personal computers. Under such circumstances, noise and electromagnetic waves radiated from the picture tube device have become a problem. Especially in Northern Europe, there is a concern that the low-frequency leakage electric field will affect the human body, and the regulation value is also set. Therefore, it is necessary to reduce the low-frequency leakage electric field leaking from the picture tube device.
No. 335144 proposes a picture tube device which reduces a low-frequency leakage electric field. As shown in FIG. 3, this picture tube device is provided with a cathode ray tube 1 and a deflection yoke 5 having a horizontal deflection coil and a vertical deflection coil arranged around the cathode ray tube 1, and a neck portion of the cathode ray tube 1 is further provided. A compensation coil 40 for inducing an electric field having a polarity opposite to that of the low frequency leakage electric field generated from the picture tube device is provided around the periphery. The compensation coil 40 is wound around a cylindrical base larger than the outer diameter of the neck portion of the cathode ray tube 1 so that one end is grounded and the other end is opened, and is called an open electrode. The low frequency leakage electric field radiated from the front surface of the cathode ray tube 1 is mainly generated from the horizontal deflection coil and the vertical deflection coil of the deflection yoke.
