Abstract: A transparent substrate includes a first principal surface; a second principal surface as a principal surface on the opposite side of the first principal surface; a lateral surface extending between the first principal surface and the second principal surface; and a first boundary surface disposed between the first principal surface and the lateral surface and having a plurality of concave portions; wherein the first boundary surface is configured such that each of the concave portions has a bottom with a curvature and that the frequency of a maximum curvature is less than 3% in a frequency distribution of the curvatures of the concave portions.

Abstract: A display device includes a display panel, and a cover member with which the display panel is covered. The cover member includes a second main surface facing the display panel, a first main surface opposite to the second main surface, and an end surface connecting the first main surface to the second main surface. A line D is defined as an imaginary line that passes through an edge E formed by the first main surface and the end surface, and members of a first layer to a nth layer (n: an inter of 2 or more) are arranged on the line D, the cover member being the first layer. A gap exists in a part between the cover member and the member of the nth layer. The display device satisfies the specific relations (1) to (3).
