摘要:
An optical sheet 10 of the present invention includes a laminate including a polarizing layer 4 containing at least one kind of a light absorbing agent and having a polarizing function, and a protective layer 1 laminated on the polarizing layer 4, in which in the polarizing layer 4, a value of a* is 0 or more and 30 or less and a value of b* is 0 or more and 30 or less in an L*a*b* color system defined by JIS Z 8781-4, and in the optical sheet 10, a size of a Q Blue value defined by Australian Standard Australia/New Zealand Standard 1067-2016 is 0.70 or more. Thus, even when the optical sheet is toned to brown, blue light can be distinguished with excellent distinguishability.
