Problems solved by technology

However, since the detached impurity gas stays between the substrates, the detachment rate of the impurity gas decreases, so it is necessary to perform a long-term initial aging treatment

Abstract

This invention provides a sealing panel (100) that can suppress a rise in discharge voltage. The sealing panel (100) comprises a resin material-containing sealing material (20) disposed on the whole periphery in a part between a pair of substrates (1,2). A getter (22), which adsorbs an impurity gas released from the sealing material (20) and an impurity gas passed through the sealing material (20), is formed continuously or intermittently along the inner periphery of the sealing material (20). Further, an ultraviolet shielding wall (24) for preventing ultraviolet light generated within the sealing panel (100) from being incident to the sealing material (20) is formed continuously along the inner periphery of the sealing material (20).

Description

technical field [0001] The invention relates to a method for manufacturing a sealing panel and a plasma display panel. [0002] this application claims priority based on Japanese Patent Application No. 2006-107547 for which it applied to Japan on April 10, 2006, and uses the content here. Background technique [0003] The plasma display panel includes a front substrate on which sustain electrodes and scan electrodes are formed, and a rear substrate on which address electrodes and phosphors are formed. The two substrates are fixed by a sealing material arranged at the peripheral portion, and a discharge gas is sealed between the two substrates. [0004] When a voltage is applied between the electrodes, the discharge gas forms plasma and emits ultraviolet rays. The ultraviolet rays enter the phosphor to excite the phosphor to emit visible light. [0005] Conventionally, low-melting-point glass has been used as a sealing material for both substrates, but a technique using a ...
