Abstract
The present invention has as its objective to provide a display panel with silver electrodes without yellowing, and a method of production such a display panel.After patterning and applying silver paste to form display electrodes on the substrate, glass paste is applied to form the dielectric layer, covering the electrodes, and both layers are simultaneously baked. Glass flit contained in the silver paste is chosen to have a lower softening point than the glass contained in the glass paste, and the baking process is divided into a first step, in which the baking temperature is equal to or higher than the softening point of the glass flit but lower than the softening point of the glass, and a second step, in which the baking temperature is higher than the softening point of the glass. This process allows a display panel to be produced with fewer bakings and reduced yellowing.
