Abstract: PROBLEM TO BE SOLVED: To stably join conductive films different in specific resistance with each other by forming a second conductive film having a specific resistance lower than that of a first conductive film, from an anode button on the first conductive film to a contact portion of a first spring. SOLUTION: From an anode button 25 on a first conductive film 24 to a contact portion 31a of a first spring 31, a second conductive film 33 having a specific resistance lower than that of the first conductive film 24. In this structure, the anode button 25 and the contact portion 31a of a first spring 31 are electrically interconnected through the second conductive film 33 to provide lower resistant portion, and the anode button 25 and a contact portion 32a of a second spring 32 are electrically interconnected through the first conductive film 24 to provide a higher resistant portion. Preferably, the first conductive film 24 has specific resistance 1-3 Ωcm in consideration of reduction of maximum instant current, and the second conductive film 33 has specific resistance 0.05-0.2 Ωcm in consideration of reduction of leaked electric field. The leaked current and the maximum instant current occurring during discharge in a valve are reduced.

Abstract: PROBLEM TO BE SOLVED: To attain a sufficient leakage electric field control effect by providing a surface treated film laminated with a reflection preventing film on a conductive film on the surface of a glass panel, and setting the surface area of its earthed electrode to a specific value or above. SOLUTION: This cathode-ray tube is provided with a surface treated film made of a reflection preventing film and a conductive film with the surface resistance value of 1×103 (Ω/(square)) or above on the surface of a glass panel 1, an earthed electrode 6 is formed on the surface treated film conductively to the conductive film, and earthed electrode 6 is conducted to a reinforcing band 7 by a conductive tape 5. The earthed electrode 6 is provided at one position at the center section of the anode terminal side on the outside of the effective screen area 9 of the glass panel 1 in a belt shape nearly in parallel with the outer edge of the glass panel 1. The contact area between the earthed electrode 6 and the conductive film is set to 500 mm2 or above, thereby the leakage electric field against the alternating electric field of the VLF band can be made 1.0 V/m or below which satisfies the TCO guide line.

Abstract: PROBLEM TO BE SOLVED: To provide a front face panel structure having sufficient leakage field suppressing effect even with a conductive film having high resistance by forming a closed loop composed of a conductive material surrounding an efficient screen region in the front face panel, and by connecting the closed loop to a reinforced band so as to be grounded as a circuit. SOLUTION: A front face panel 1 is formed with a surface treatment film composed of a bottommost-layer conductive film and two layers of low reflecting films placed thereon on its surface and an explosion-proof metal reinforced band 7 is installed in its circumference. A conductive tape 5 made of Al is affixed into a closed loop as surrounding an effective screen region 9 on the surface of the surface treatment film and two conductive tapes 5 are independently affixed to each long sides 12 and short sides 13. The log sides 12 are conducted with the reinforcing band 7, the short sides 13 are formed by affixing the conductive tapes 5 across the both of the surface treatment film and the short sides of the reinforcing band 7, and the conducive tapes 5 are grounded through the reinforcing band 7. Even a conductive film having a resistance value 1×103 Ω/(square) or more can provide a leakage field suppression effect.
