Abstract:
The present invention provides an image display device capable of displaying a good image by suppressing yellowing of a glass substrate, and a high-yield manufacturing method of the glass substrate. The image display device is formed of a front-side glass substrate and a back-side glass substrate. In this manufacturing method, a glass substrate is used as the front-side glass substrate when Sn++ content in the glass substrate is a predetermined value or less, and the glass substrate is used as the back-side glass substrate when the Sn++ content exceeds the predetermined value.
Abstract:
A method of manufacturing a plasma display panel, whose glass substrate is not tinged and luminance is high, is provided, even when silver material is used. A layer including silver compounds, which include sulfur generated on a surface of an electrode by reacting on sulfur in air, is removed before a forming process of a dielectric layer. Then decomposition of the compound is restricted in a firing process of the dielectric layer. Even when the electrode having the silver material with high electrical conductivity is used, yellow coloration on the glass substrate is prevented. As a result, a high quality plasma display panel which does not decrease in luminance is provided.
Abstract:
An electrode plate, a method of manufacturing the same, a gas discharge panel using an electrode plate, and a method of manufacturing the same are provided by incorporating a relatively simple structure, which can keep electrodes formed on a plate from peeling or becoming misaligned. In the electrode plate, at least one electrode is formed and adhered to a main surface of a plate by a thick film or thin film formation method, wherein of all ends of the electrode, at least an end opposite to an end at a power supply point is adhered to the main surface of the plate with stronger adhesion than the other parts of the electrode. When this electrode plate is used as a front panel glass having a plurality of pairs of display electrodes in a gas discharge panel, at least an end of each bus line opposite to an end at a power supply point is firmly adhered to the surface of the front panel glass, thereby keeping the bus lines formed on respective transparent electrodes from warping and peeling away or becoming misaligned. Such a gas discharge panel can deliver excellent display performance.
