Embodiment 1
[0070] The glass paste of the Example was produced according to the procedure shown below. First, various inorganic raw materials were weighed so that the glass powders had the prescribed compositions A to J shown in Table 1, and the prescribed amounts were mixed for 4 hours using a small shaker mixer to prepare raw material mixing batches. Heat the mixed batch of raw materials to a temperature above 1000°C in a platinum crucible or a quartz crucible to promote the chemical reaction between the raw materials, cause a vitrification reaction, melt for more than 5 hours, and use a homogenization mechanism such as stirring to form Homogeneous molten state. Next, the molten glass flows out from the molten glass outlet provided at the bottom of the crucible, roll-formed into a film-shaped glass of about 1 mm, and the film-shaped glass that is still at a high temperature after forming is put into a water-stored SUS glass. In a container, thermal shock is applied while preventing the...
Embodiment 2
[0081] Next, the leak property after forming the sealing structure using the glass paste of the Example was evaluated in the following procedure.
[0082] First, glass powder, a filler, and an organic component were prepared, weighed, and mixed in the same procedure as in Example 1 to prepare glass pastes of Sample Nos. 1 to 10 in Example 1. Next, using these glass pastes, use screen printing on the plate glass (dimensions 10×10×0.7 mm) for PDP prepared in advance, and form a similar width along the edge on the side of the light-transmitting surface of the plate glass. In the method of printing cross-sections of partition walls with a size of 100 μm and a height of 100 μm, multiple layers of printing are performed to form a structure that has a character-shaped appearance. Then, pre-firing was performed with the printed sample facing upward, and another plate glass for PDP having the same size was loaded so as to sandwich the structure made of glass paste formed by printing. ...
