PURPOSE: To form beautiful images having no distortions by enabling a thin film aperture electrode body to be secured with accuracy in no wrinkle plane. CONSTITUTION: Since the aperture electrode body 10 is applied with tension from the supports 10a, 10b, at the time when the aperture electrode body 10 Is pressed against interposers 26, 27, forces F function on the Interposers 26, 27 to press them back. The interposers 26, 27 formed in a curved shape eventually allow the tangential forces F1 of pressing back forces F to function to prevent the occurrence of wrinkles of the aperture electrode body 10. Also, when the aperture electrode body 10 is mounted on the curved interposers 26, 27, it contacts in turn from the most projected central part to the end parts, thus wrinkles become hard to occur thereon. |
