Abstract: PROBLEM TO BE SOLVED: To enable the easy connection of a conductive layer by connecting the conductive layer to grounding electrodes via grooves for connection formed by penetrating through the nonconductive layer and conductive layer formed on the filter for a display device from its surface and the electrode layers covering the peripheral parts thereof. SOLUTION: After the filter 10 for the display device is stuck to the panel surface of a cathode ray tube, notches 50 (grooves for connection) are put usually at four corners of the points to be connected to the filter 10 for the display device at a invalid screen. The notches 50 are so formed as to penetrate at least the conductive layer 15. The grooves for connection and the peripheral parts thereof are covered with conductive materials to form the electrode layers 32 and to fill the grooves 50 for connection with the electrode layers 32. Fissures and cracks are generated by the strains generated at the time of forming the grooves on the peripheries of the grooves 50 for connection of an antireflection film 17 covering the conductive layer 15 by the formation of the grooves 50 for connection. The layer of the conductive layer is sometimes exposed on the inside surface of the grooves 50 for connection. Then, the connection of the electrode layers 32 to the conductive layer 15 is obtd. from the cracked parts of the antireflection film 17 on the inside surface of the grooves 50 for connection or the peripheries thereof.
