Abstract

PURPOSE: To prevent deformation due to heat by electrically connecting a metal reflecting film inside panel and funneled conductive film by using a conductive elastic piece independently separated from shadow mask and its supporting and fitting parts mechanically.
CONSTITUTION: The fitting base 31 for the contact spring 15, made of Fe-Ni alloys having the same thermal expansion coefficient as that glass of the panel 11, for example, is adhered to the surface of the panel 11 with a frit glass. Also, the base 31 is made of two plates doubled, so that the development of small cracks in the panel 11 due to the heat of welding can be prevented when welding the contact spring 15 to the base 31. And, in order to assure electrical connection, the graphite 23 is coated between the metal reflecting film 22 and the base 31 or the contact spring 15.
