Ink for a display panel and method for producing plasma display panel using the ink

A manufacturing method for a plasma display panel that includes a first panel and a second panel, the method having a structural layer formation step of forming a structural layer of the first panel, and a sealing step of sealing the first panel to the second panel and filling a space between the sealed panels with a gas medium, wherein the structural layer formation step has:

• an application substep of applying an ink for a display panel to the first panel using an inkjet method, the ink including a powder material used in forming the structural layer, water or a water-miscible solvent, a binder formed from a water-soluble resin, and a plasticizer;
• and
• a baking substep of burning-off the binder and the plasticizer included in the applied ink.

A manufacturing method for a plasma display panel that includes a panel having a plurality of porous barrier ribs formed in rows, the method having a reflective layer formation step of forming a reflective layer in a rib gap between adjacent barrier ribs, wherein the reflective layer formation step has:

• an application substep of applying in the rib gap a reflective layer ink including a powder material used in forming a structural layer of the display panel, water or a water-miscible solvent, a binder formed from a water-soluble resin is included in a range of 1 wt % to 20 wt % inclusive of the ink at a time of application, and a plasticizer, the powder material includes a white pigment having an average particle size in a range of 0.05 μm to 2 μm inclusive, and a glass frit material having an average particle size in a range of 0.1 μm to 3 μm inclusive;
• and
• a baking substep of burning-off the binder and the plasticizer included in the applied reflective layer ink wherein the structural layer is a reflective layer.

A manufacturing method for a plasma display panel that includes a panel, the method having a shading film formation step of forming a shading film on a principal surface of the panel, wherein the shading film formation step has:

• an application substep of applying to the principal surface of the panel a shading film ink including a powder material used in forming a structural layer of the display panel, water or a water-miscible solvent, a binder formed from a water-soluble resin included in a range of 1 wt % to 20 wt % inclusive of the ink at a time of application and a plasticizer wherein the structural layer is a shading film, and the powder material includes a black pigment, and a glass frit material having an average particle size in a range of 0.1 μm to 1 μm inclusive;
• and
• a baking substep of burning-off the binder and the plasticizer included in the applied shading film ink.

A manufacturing method for a plasma display panel that includes a panel, the method having a sealing layer formation step of forming a sealing layer around a perimeter of the panel, wherein the sealing layer formation step has:

• an application substep of applying a sealing layer ink to the perimeter of the panel, the sealing layer ink including a powder material used in forming a structural layer of the display panel, water or a water-miscible solvent, a binder formed from a water-soluble resin, the binder is included in a range of 1 wt % to 20 wt % inclusive of the ink at a time of application wherein the structural layer is a sealing layer, and the powder material includes a glass frit material having an average particle size in a range of 0.1 μm to 3 μm inclusive, and a plasticizer;
• and
• a baking substep of burning-off the binder and the plasticizer included in the applied sealing layer ink.
