Abstract:
1. A substrate for an electronic device, comprising: a translucent glass substrate having a first main surface and a second main surface, the first and second main surfaces facing each other, the translucent glass substrate comprising a glass layer formed on the first main surface of the translucent glass substrate; and an electrode pattern formed on the first main surface of the translucent glass substrate, wherein the first main surface is a surface which forms waviness made up of curved faces, the waviness of the surface has a wavelength Rλa of greater than 50 μm, a ratio Ra/Rλa of waviness roughness Ra of the surface which forms a waviness to the wavelength Rλa of the waviness is from 1.0×10 the glass layer having a second surface abutting on a side of the first main surface of the translucent glass substrate and a first surface, opposite to the second surface, which forms waviness made up of curved faces, the translucent glass substrate further comprising a scattering layer formed on the first main surface of the translucent glass substrate and made from a glass comprising a base material which has a first refractive index for at least one of wavelengths of transmitted light and a plurality of scattering materials being dispersed in the base material and having a second refractive index different from the first refractive index of the base material, and distribution of the scattering materials in the scattering layer diminishes from the inside of the scattering layer toward a translucent electrode formed as a first electrode on the first surface, wherein a density ρ
