Abstract

PURPOSE:To obtain stable charging prevention effect by providing a strip conductor in press contact onto a CRT screen face and provided with ground to the surrounding of the front edge of the CRT tube. CONSTITUTION:A metallic plate or a metallic fiber 6 is in close contact onto a slope at the surrounding of the front edge of the tube face of the CRT 5 and it is connected to a ground potential such as a metal-made chassis or case of the CRT display device. Thus, the charging is reduced.
