ABSTRACT OF THE DISCLOSURE (Fig. 2) A protective screen for a visual display unit (VDU) comprises a filter layer which is operative to protect the operator from electrostatic and electromagnetic fields and from residual radiation of a cathode ray tube (CRT) of the VDU. The VDU comprises a body structure for the CRT and the screen comprises a support frame for the filter layer, an intermediate support between the frame and the body structure of the VDU and a pair of fixing plates which are adjustable both front to back and angularly, for fixing the intermediate support to the upper portion of the body structure independently of the specific form of the body structure. The frame of the screen is also pivoted to the intermediate support to permit the filter layer to be disposed in front of the display surface of the CRT or be swung up to expose the CRT screen.
