Abstract
A flat cathode-ray tube includes a three-component structure of a front panel, a screen panel, and a funnel which are jointed by frit paste. The funnel is inwardly projected from the front panel and the screen panel in the horizontal direction to form a level-difference portion for storing fused frit over the whole inner periphery of the joint surface, whereby occurrence of defected sealing can be decreased, and occurrence of resultant air leakage can be decreased.
