<p>In a monitor 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 (2) is disposed to surround the display area of the front face of a cathode ray tube, and a leakage electric field compensation signal, the level of which varies according to fly-back pulse, is applied to this electrode, with reverse phase. <IMAGE></p> |
