GLASS PLATE PRODUCTION METHOD AND GLASS PLATE

摘要

A glass plate 12 equipped with a light-incident-side beveled surface 40 that is positioned in a manner such that a line segment L1 connecting a first intersecting point P1 at which the light-incident-side beveled surface 40 and a light-emitting surface 26 intersect and a second intersecting point P2 at which the light-incident-side beveled surface 40 and an angled surface 48 intersect is angled relative to a light-incident end surface 28 by a prescribed slope angle θ1. The glass plate 12 is further configured in a manner such that a line segment L2 connecting the second intersecting point P2 and a third intersecting point P3 at which the angled surface 48 and the light-incident end surface 28 intersect is angled relative to the light-incident end surface 28 by a slope angle θ2, which is smaller than the slope angle θ1 and satisfies the equation 0
