Document Type and Number:
Japanese Patent JP5862736
Kind Code:
B2
Abstract:
Provided is a substrate for an electronic device for providing an electronic device having a long-life and a high reliability in which exfoliation or deterioration of a wiring is inhibited by embedding the wiring therein while maintaining smoothness of the surface. The substrate is a substrate 100 for an electronic device, including a first and a second main surfaces facing each other, in which an electrode wiring is formed on the first main surface. The substrate 100 for an electronic device includes a glass substrate 101, an auxiliary wiring pattern 200 formed on the first main surface on the glass substrate 101, and a translucent glass layer 102 formed on the surface of the glass substrate 100 to cover the upper layer of the auxiliary wiring pattern 200, in which through-holes H exposing the auxiliary wiring pattern 200 are formed in a portion of the glass layer 102. Since the entire auxiliary wiring pattern 200 is confined to the glass layer 102 except for the connection area in which the auxiliary wiring pattern 200 is exposed through the through-holes H, it is possible to provide a stable and long-life auxiliary wiring pattern causing no concern for deterioration of the auxiliary wiring pattern 200. Furthermore, the surface of the glass layer obtained by vitrification is smooth, hence the film thickness of a functional layer including an electrode wiring formed on the upper layer of this smooth surface can be made stable and uniform.
