ABSTRACT:
A CRT display device having a housing which includes a ground terminal and an opening, and a CRT (cathode-ray tube) which includes a shadow mask, a tube face of the CRT being irradiated with an electron beam through the shadow mask, thereby displaying a picture in a whole region of the opening; comprising an electrically conductive shield which confronts a part of the CRT display device which extends from a peripheral edge of the shadow mask to a peripheral edge of the tube face. The shield is connected to the ground terminal. The shield makes it possible to readily fabricate a CRT display device which can prevent alternating electric fields and electromagnetic waves from leaking out of the tube face without degrading the display performance of the CRT.
