Abstract
Provided is a curable composition that can form a lens having excellent visibility, antiglare effects, and contrast-enhancing effects by suppressing thermal degradation of a tetraazaporphyrin compound. The curable composition according to the present disclosure includes silsesquioxane containing a cyclohexene oxide group, and a tetraazaporphyrin compound having an absorption peak in a wavelength region of from 570 to 605 nm, in which a content of the tetraazaporphyrin compound is from 1000 to 10000 ppm by weight of a content of the silsesquioxane.

A hard coating film comprising a cured product of a curable composition, said curable composition comprising:
- silsesquioxane containing a cyclohexene oxide group;
- and a tetraazaporphyrin compound having an absorption peak in a wavelength region of 570 to 605 nm,
- wherein a content of the tetraazaporphyrin compound is from 1000 to 10000 ppm by weight of a content of the silsesquioxane, and
- wherein a luminous transmittance of the hard coating film is 78% or greater.
