    Abstract: A translucent substrate may include a transparent support substrate, and a light extracting layer formed on the transparent support substrate, including a glass material having a first refractive index in a range of 1.6 to 2.2 for D line, and a scattering material having a second refractive index different from the first refractive index for the D line. The light extracting layer may have a surface formed with a plurality of projections including at least one of an approximately pyramid-shaped projection having one peak point and an approximately triangular prism-shaped projection having one peak edge. An inclination angle formed by an edge and a base edge of an approximate triangle, obtained in a vertical cross section passing through the peak point or the peak edge of the projection, may be in a range of 10° to 60°.

  • Patent number: 8530748
    Abstract: 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.
