GLASS, CHEMICALLY STRENGTHENED GLASS, EXTERIOR MEMBER, AND ELECTRONIC DEVICE

摘要

In glass or chemically tempered glass containing a coloring component, when chromaticity of a major surface is measured on the glass in a state of a glass plate with a 0.8 mm thickness, at least one of an absolute value of a difference (Δa*(D65−F2)) and is an absolute value of a difference (Δa*(A−F2)) is 2.10 or more, where the difference (Δa*(D65−F2)) is a difference between a chromaticity a* value of reflected light by a D65 light source and a chromaticity a* value of reflected light by an F2 light source in an L*a*b* color system and the difference (Δa*(A−F2)) is a difference between a chromaticity a* value of reflected light by an A light source and the chromaticity a* value of the reflected light by the F2 light source in the L*a*b* color system.

1. A glass containing a coloring component,
wherein, when chromaticity of a major surface is measured on the glass in a state of a glass plate with a 0.8 mm thickness, at least one of an absolute value of a difference (Δa*(D65−F2)) and an absolute value of a difference (Δa*(A−F2)) is 2.10 or more, where the difference (Δa*(D65−F2)) is a difference between a chromaticity a* value of reflected light by a D65 light source and a chromaticity a* value of reflected light by an F2 light source in an L*a*b* color system, which difference is expressed by the following expression (1), Δa*(D65−F2)=a* value (D65 light source)−a* value (F2 light source) . . . (1), and the difference (Δa*(A−F2)) between a chromaticity a* value of reflected light by an A light source and the chromaticity a* value of the reflected light by the F2 light source in the L*a*b* color system, which difference is expressed by the following expression (2), Δa*(A−F2)=a* value (A light source)−a* value(F2 light source) . . . (2).
