METHOD FOR PRODUCING ELECTRONIC DEVICE SUBSTRATE, METHOD FOR MANUFACTURING ELECTRONIC DEVICE, ELECTRONIC DEVICE SUBSTRATE, AND ELECTRONIC DEVICE

摘要

A method for producing a substrate for an electronic device, that can improve light extraction efficiency, can easily produces and has high liability is provided. The method includes: a step of heat-melting a glass raw material or a glass to produce a molten glass; a forming step of continuously feeding the molten glass to a bath surface of a molten metal bathtub accommodating a molten metal to form a continuous glass ribbon 6; a step of feeding a glass powder M having a desired composition on the continuous glass ribbon 6 and melting or sintering the glass powder M to form a scattering layer; a step of gradually cooling the scattering layer-attached continuous glass ribbon; and a step of cutting the scattering layer-attached continuous glass ribbon gradually cooled to obtain a scattering layer-attached glass substrate.
