Anode substrate for a display device, e.g. a fluorescent display device, a field emission device or a plasma display panel

摘要

A low melting glass smoothing layer (2) is provided on the color filters on the interior surface of a glass sheet (1) of an anode substrate (11) for a display device. An anode substrate for a display device has a smoothing layer (2) on the interior surface of a glass sheet bearing color filters. The smoothing layer (2) consists of a low melting glass which has a softening point below the deformation point of the glass sheet and a deformation point at least as high as the heating temperature used in a subsequent production stage. An Independent claim is also included for production of an anode substrate by forming color filters (R, G, B) on the interior surface of a glass sheet (1), applying a low melting glass as described above to form a smoothing layer (2) on the interior surface and forming a conductive film (4) on the smoothing layer (2). Preferred Features: The low melting glass is a lead-free ZnO glass selected from ZnO-B2O3-SiO2 and Bi2O3-ZnO-SiO2 glasses.
