Abstract:
A color conversion composition is configured to convert incident light into light having a wavelength longer than that of the incident light. The color conversion composition includes: an organic luminescent material (A) having a full width at half maximum of a peak of 10 nm or larger and 50 nm or smaller, the peak indicating a maximum radiant intensity in an emission spectrum; and a resin (B) having an alicyclic structure, a ratio of a repeating unit having the alicyclic structure in the resin being 50% by weight or higher in a total amount of the resin.
