| 20080203894 | DISPLAY DEVICE - The purpose of the invention is to improve the mass productivity of display devices by using a glass substrate that prevents the degradation of an electrode caused by glass of the display device. The present invention provides a flat panel display device containing at least two substrates and a light emitting part provided between the two substrates, wherein at least one substrate of the two substrates contains SiO | 08-28-2008 |
| 20080211384 | Field Emission Display and Glass Frit - Constituent elements of a glass frit for fixing spacers propagate along the spacers and migrate to electron emitters to deteriorate the electron emitters, and thereby silhouetting shadows of the spacers on a screen are suppressed. In an image display which is equipped with a rear substrate provided on its inner surface with electron emitters, a front substrate facing the rear substrate, provided on its inner surface with a phosphor pattern having an array corresponding to the electron emitters, and having an outer surface serving as a display surface, and in which a gap between the substrates is held by glass-made spacers, propagation along the spacers and migration to the side of the electron emitters of the constituent elements of the glass frit for fixing spacers is prevented by fixing oxide crystal particles on the spacer surface, or by fixing at least a part of the spacer to the front panel by an adhesive layer comprising a conductive glass a part of which is crystallized. | 09-04-2008 |
| 20080238292 | PLASMA DISPLAY PANEL AND METHOD FOR PRODUCING THE SAME - A plasma display panel comprising a front substrate and a back substrate formed opposite each other and bonded to each other at the peripheries, electrodes formed on the front substrate, a dielectric layer formed on the electrodes, a protective layer formed on the dielectric layer, another electrode and another dielectric layer formed on the back substrate, barrier ribs to keep spaces between the front substrate and the back substrate, and fluorescent materials packed in the spaces formed by the barrier ribs, the front substrate, and the back substrate. The barrier ribs include glass at least containing oxide of tungsten, phosphorus, barium, and vanadium. | 10-02-2008 |
| 20080238315 | PLASMA DISPLAY PANEL - To prevent occurrence of abnormal discharge which would reduce the quality of images in a PDP. At least one of an address electrode, a bus electrode, a bus main electrode, and a black electrode of a display electrode formed on a substrate is formed of metal particles and high-resistance glass to dissipate charge accumulated on a dielectric through the high-resistance glass and to prevent charging in a glass component itself, thereby reducing abnormal discharge. The high-resistance glass is preferably realized by vanadium phosphate glass containing vanadium, phosphorus, antimony, and barium. The metal particles desirably contain flaky particles. | 10-02-2008 |
| 20080238316 | PLASMA DISPALY PANEL AND MANUFACTURING METHOD OF THE SAME - The purpose of the present invention is to provide a plasma display panel containing black colored parts which have high resistant against degradation in blackness or peeling by high-temperature oxidation. The present invention provides a plasma display panel comprises: a front substrate and a rear substrate, edge portions of which are adhered to each other, the both substrates being provided opposite to each other; an electrode provided on the front substrate, a dielectric layer provided on the electrode; a protective layer provided on the dielectric layer; a black compound layer having an opening on the protective layer; an electrode and a dielectric layer provided on the rear substrate; a barrier rib holding a gap between the front substrate and the rear substrate; and a phosphor filled in a space formed by the barrier rib, wherein the black compound layer is formed on the front substrate side seen from the barrier rib, wherein the black compound layer comprises a mixture of a ceramics filler and a glass, and wherein the glass comprises a phosphate glass containing a transition metal element. | 10-02-2008 |
| 20080238821 | PLASMA DISPLAY PANEL - To prevent sucking of a sealing material in steps of sealing and exhaust of a plasma display panel. The plasma display panel includes a front substrate and a rear substrate, in which the peripheries thereof are sealed by a glass sealing material. A sealing portion formed by the glass sealing material is formed of a multi-layered structure including at least two types of glass with different softening points. The entirety or part of the sealing portion on an inner side of the panel is formed of glass with the highest softening point. Since the high-temperature softened glass serves as a barrier for preventing sucking of the low-temperature softened glass into the panel, it is possible to prevent sucking of the sealing material into the panel. This can improve image display characteristics. | 10-02-2008 |
| 20090098788 | PLASMA DISPLAY PANEL AND MANUFACTURING METHOD THEREOF - In a plasma display panel where a discharge space is partitioned by lattice-shaped barrier rib which comprises vertical ribs and horizontal ribs, a manufacturing method for the plasma display panel is acquired. This manufacturing method is designed for allowing substantially-linear exhaustion-use through holes parallel to the vertical ribs to be formed on the horizontal ribs with the execution of a simple and convenient processing step. The plasma-display-panel manufacturing method thus acquired includes steps of forming a glass-containing material, which becomes step-difference, into a stripe-shaped configuration at positions of the vertical ribs on a coated film of a barrier rib material formed on a glass substrate, and after that, performing patterning of the lattice-shaped barrier rib. | 04-16-2009 |
