This nonaqueous electrolyte secondary battery is provided with an electrode body that is obtained by alternately laminating a plurality of positive electrodes and a plurality of negative electrodes, with separators being interposed therebetween. Each separator is configured of a porous resin substrate and a porous heat-resistant layer that is formed on one surface of the resin substrate and has a larger surface roughness than the resin substrate. The electrode body comprises: bonding particles that bond a negative electrode and a heat-resistant layer with each other; and bonding particles that bond a positive electrode and a resin substrate with each other. The mass of the bonding particles per unit area in a first interface between the negative electrode and the heat-resistant layer is larger than the mass of the bonding particles per unit area in a second interface between the positive electrode and the resin substrate.

In a plasma display panel, in which an area percentage of the display electrodes in an area of an image display region of the front panel is expressed by a longitudinal axis, and a difference between a coefficient of expansion of the front substrate from room temperature to 300&#xb0; C. and a coefficient of expansion of the dielectric layer from room temperature to 300&#xb0; C. is expressed by a lateral axis, the difference between the coefficients of expansion and the area percentage stay within a region formed by connecting coordinates (35&#xd7;10/&#xb0; C., 60%), coordinates (8&#xd7;10/&#xb0; C., 60%), coordinates (5&#xd7;10/&#xb0; C., 40%), and coordinates (23&#xd7;10/&#xb0; C., 40%) in the mentioned order with a straight line where the straight line is included.

Plasma display panel having low residual stress

A plasma display panel is formed of a front panel including display electrodes, a dielectric layer, and a protective layer which are formed on a glass substrate, and a rear panel including electrodes, barrier ribs, and phosphor layers all of which are formed on a substrate. The front panel and the rear panel confront each other, and peripheries thereof are sealed to form a discharge space therebetween. The dielectric layer of the front panel contains BiOand at least CuO and CoO, and the total content expressed in mole % of CuO and CoO falls within a range from 0.03% to 0.3%.

Plasma display panel free from yellowing

A plasma display panel is formed of front panel including at least display electrodes, dielectric layer that are formed on glass substrate, and a rear panel including electrodes, barrier ribs, and phosphor layers that are formed on a substrate. Dielectric layer is formed of multiple layers, i.e. lower dielectric layer and upper dielectric layer, and these layers are made of identical material to each other, and the material contains CaO and BaO, and the content of CaO is greater than that of BaO.

Plasma display panel having a plurality of layers containing calcium oxide and barium oxide

A plasma display panel is formed of a front panel including display electrodes, a dielectric layer, and a protective layer that are formed on a glass substrate, and a rear panel including electrodes, barrier ribs, and phosphor layers that are formed on a substrate. The front panel and the rear panel are faced with each other, and peripheries thereof are sealed to form a discharge space therebetween. The dielectric layer of the front panel contains BiOand at least CaO and BaO, and the content expressed in mole % of CaO is greater than that of BaO.
