Abstract
PURPOSE:To obtain a CRT filter which prevents imprinting without degrading resolution and is formed to obviate charging of static electricity on the surface of the CRT filter by incorporating a transparent conductive layer on the surface or in the filter. CONSTITUTION:This CRT filter has the shape to provide a tight contact with the CRT surface and has >=30% light ray transmissivity at 550nm wavelength. The glossiness Gs (60 deg.) on the filter surface on the side opposite to the CRT is 40-90% and the transparent conductive layer is provided on the surface or in the filter. The transparent conductive layer is required to have the electrical conductivity of the extent at which the static electricity charged in the CRT and the CRT filter can be removed. The CRT filter which prevents the imprinting on the surface, does not degrade the resolution in the corner part of the image plane and is capable of preventing the charge of the static electricity is thereby obtd.
