摘要： A glass sheet includes a first surface; a second surface facing the first surface; and at least one first edge surface disposed between the first surface and the second surface. A mean height We of a waviness profile element of the first edge surface and a mean length WSm of the waviness profile element satisfy Formula (1) below. W c ≦ 1 0.6  π 2  ( n g - 1 ) · WSm 2 ( 1 ) where ng represents a refractive index of the glass sheet.

摘要： A glass includes a first surface; a second surface that faces the first surface; at least one first end surface arranged between the first surface and the second surface; and at least one first chamfering surface connecting the first surface or the second surface with the first end surface. A surface roughness Ra of the first chamfering surface is 0.4 μm or less.
