Filed: 2001-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a plasma display panel and its manufacturing method which can cope with realization of high precision and resolution without reducing productivity. SOLUTION: By a screen printing method, fluorescent material layers 10R and 11R, fluorescent material layers 10G and 11G as well as fluorescent material layers 10B and 11B are formed in respective columns. As a result, between a region prolonged in a column direction of an insulating wall 9 and a protective layer, a space having a thickness of the same degree as that of the fluorescent material layers 10R, 10G and 10B exists. Therefore, reduction in evacuation efficiency and encapsulation efficiency of a discharge gas can be avoided. As a result, the appropriate discharge gas is capable of surely existing in a discharging space, and a superior display characteristic can be obtained. Further, because display cells next to each other in the column direction are separated with an insulating wall 9, an erroneous discharge is not generated. Accordingly, it is possible to make a non-discharge gap narrower, and possible to easily cope with the realization of the high precision and resolution.
