Abstract: A display device includes a front case; a cathode ray tube mounted on the front case; a main circuit board mounted on the rear side of the cathode ray tube; a circuit board frame, mounted to one among the front case and the cathode ray tube, to support the circuit board; a nonflammable and fire-retardant shield case to contain a fire that may break out in the interior of the display device, while providing a shielding effect which minimizes the radiation of electromagnetic waves generated by the display device and protects the display device from external electromagnetic interference; and a rear case that is combined with the front case to encase the interior of the display device. A top surface of the shield case includes an anode cap shield which protrudes upwardly from the surface to a fixed height to form openings on either side of an anode cap shield.
