    摘要: A display device comprising a cathode ray tube is provided with a holder which comprises a faceplate and which is arranged in front of the display window. The space between the faceplate and the display window is filled with a liquid or a gel having a refractive index which differs maximally 0.25 from the refractive index of the display window and faceplate. An improved image display, in particular an improved contrast and a flatter image are obtained. In a further embodiment, the holder is fixed to the implosion protection band of the cathode ray tube.
