Abstract
The present invention provides a curable composition containing a compound represented by General Formula A and a compound represented by General Formula B.ArL-Sp-Pol) (General Formula A) In General Formula A, Ar represents an n-valent group containing a nitrogen-containing fused aromatic ring as a partial structure; In General Formula B, R′, R″, and R′″ are each independently a hydrogen atom or a substituent; R′ and R″ or R″ and R′″ may be bonded to each other to form a ring that may have a substituent; and W is a hydrogen atom or a substituent. Using the curable composition of the present invention, it is possible to form a cured product having a small Abbe number, a large partial dispersion ratio, and high light stability.
