Abstract: PROBLEM TO BE SOLVED: To eliminate generation of an unusual luminant phenomenon by remaining of impurity gas, such as water, CO2 , and the like, in a panel. SOLUTION: The impurity gas, which is hard to remove after becoming panel, is effectively eliminated by establishing the impurity gas elimination process 11, in which a simple substrate is exposed to heating or electric discharging in advance of a sealing process 12. Moreover, making it a dry atmosphere or a vacuum atmosphere, including the process after the simple substrate processing and its conveyance course prevents re-adhesion of impurity gas. The panel with little impurity gas can be realized by this, it is hard to generate unusual luminant, and it also improves panel reliability.

Abstract: PROBLEM TO BE SOLVED: To solve problem with the introduction of dry gas into a panel during sealing for the purpose of avoiding thermal degradation of a blue phosphor during a sealing process, that bias occurs within the plane of the panel during the introduction and evacuation of the gas, causing in-plane nonuniformity of the characteristics of the blue phosphor.
SOLUTION: A configuration is chonsen in which barrier ribs differ in length in a portion corresponding to the outside of at least one of display areas, along the longitudinal direction of the barrier ribs. Moreover, a configuration is chosen in which the length of barrier ribs increase or decrease for every predetermined number of ribs in a monotonous fashion from one substrate end parallel to the longitudinal direction of the barrier ribs to the other. This enables gas to fully flow even at the center of the panel where gas cannot flow easily in conventional panels, and the in-plane uniformity of the blue phosphor can be secured.
