To provide a curable composition that includes a light-emissive semiconductor particle and is unlikely to cause generation of outgas.

A curable composition comprising: a semiconductor particle (A); a polymerizable compound (B); a polymerization initiator (C); and an antioxidant (D); wherein a formula (i) is satisfied:

[00001]$\begin{array}{cc}11.5M_B/M_{C}150& \left(i\right)\end{array}$ wherein M.sub.B represents a content ratio (% by mass) of the polymerizable compound (B) and Me represents a content ratio (% by mass) of the polymerization initiator (C), all based on a total amount of the curable composition.
