Abstract
In a monitoring device which forms a display image by using a cathode ray tube, leakage of electric field from the front side of the cathode ray tube is diminished with a simple construction. A leakage electric field compensation electrode is disposed to surround the display area of the front face of a cathode ray tube, a leakage electric field compensation signal, the level of which corresponds to fly-back pulse, is applied to this electrode, and the electric field compensation electrode corresponding forms a compensating electric field that cancels the leakage electric field.
