Abstract: A method for manufacturing a glass substrate for a display includes a step of producing a glass substrate and a step of performing a surface treatment on one glass surface of major surfaces of the glass substrate to form surface unevenness. The surface treatment is performed such that protruded portions having a height of 1 nm or more from the surface roughness central plane of the surface unevenness are dispersedly provided on the glass surface after the surface treatment and the area ratio of the protruded portions with respect to the area of the glass surface is 0.5-10%. Using this glass substrate, semiconductor elements are formed on a major surface of the glass substrate opposite to the glass surface. Accordingly, a display panel is produced.
