A technique which enables screen printing on a large printed object is provided. A screen frame of a screen mask has a lower surface (third surface), a screen-mesh holding unit which holds a screen mesh, a surface (fourth surface) which is different from the lower surface, and a screen-frame fixing unit which is fixed in a state in which a first contact region which is a part or the entirety of the surface is in contact with a screen-frame holder of a printing device. The position of the first contact region in a cross section of the screen frame cut from the upper surface toward the lower surface is present above the lower surface.

A plasma display panel includes a front substrate and a rear substrate that are opposed to each other with a discharge gas space between them, and a sealing material for sealing the front substrate and the rear substrate at their peripheral portions. The sealing material contains an appropriate quantity of spacers so that a thickness of the plasma display panel is uniform along the entire perimeter of the sealing portion between the front substrate and the rear substrate. The sealing material contains non-porous beads as the spacers, preferably at a ratio within the range of 0.05-2.0 wt %.

A method for manufacturing a plasma display panel is provided. The method includes making a front substrate and a rear substrate individually and applying a low melting point glass paste including non-porous bead onto a portion of the front substrate or the rear substrate so that the applied low melting point glass paste forms a frame-like shape having a height greater than that of the structural member. The method includes assembling the front substrate and the rear substrate in a face-to-face relation with each other and burning the applied low melting point glass paste while vacuuming a discharge gas space between the front substrate and the rear substrate so as to seal the front substrate and the rear substrate.

A screen mask includes a screen mesh with a tensioning force of 196 to 392 N/mm; a tension mesh with a tensioning force of 49 to 98 N/mm; a resin plate (fixing part) arranged so as to surround the outer periphery of the screen mesh for fixing a part of the tension mesh with a tensioning force of 392 to 980 N/mm; and a screen frame. A length Ls of the screen mesh in a first direction intersecting a direction in which a squeegee squeegees on the screen mesh when performing a screen printing is 0.6 to 0.9 times a length Lt of the tension mesh in the first direction, a length Lk of the resin plate, the length Ls, and the length Lt in the first direction satisfy a relationship Lk=a(Lt+Ls)/2, where “a” is a coefficient in a range of 0.5 to 1.2.

摘要:
A method of forming an electrode for a plasma display panel, in which the method includes the steps of forming a first metal film on a second metal film after formation of the second metal film on a substrate, forming a resist pattern on the laminated metal films, and etching the laminated metal films with an etching solution, thereby forming an electrode of the laminated films. A first metal is different from a second metal, and the first metal and the second metal have properties such that the surface potential of the first metal decreases when the first metal and the second metal in the state of being soaked in an etching solution of the first metal are short-circuited. During or after the formation of the first metal film, a diffusion step is performed in which an atmospheric temperature is kept at such a temperature that the metal atoms of the second metal film diffuse in and on the surface of the first metal film.
