Patent number: 8530748Abstract: A substrate includes an auxiliary wiring pattern formed on a first main surface of a glass substrate in a grid-like pattern arranged horizontally and vertically, and a translucent glass layer formed on a surface of the glass substrate to cover the first main surface and the auxiliary wiring pattern. Through-holes exposing the auxiliary wiring pattern are formed in a portion of the translucent glass layer formed on the auxiliary wiring pattern, in each side of each grid of the grid-like pattern at uniform intervals. The substrate may be used in 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.Type: GrantFiled: April 5, 2011Date of Patent: September 10, 2013Assignee: Asahi Glass Company, LimitedInventors: Nobuhiro Nakamura, Yumiko Aoki, Naoya Wada
