Abstract
A curable composition capable of manufacturing a cured product having a high refractive index is provided. The curable composition contains a polymerizable compound represented by formula (1) and inorganic particles. In formula (1), La represents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having an aromatic group, Ar represents an aromatic group, and R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents.

A curable composition comprising:
- a polymerizable compound represented by formula (1):
- where La represents a divalent linking group, and the divalent linking group includes at least one of a divalent aromatic group, a divalent polycyclic aliphatic group and an alkylene group having at least an aromatic group,
- Ar represents an aromatic group, and
- R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents;
- and
- inorganic particles.
A polymerizable compound represented by formula (2):
- where Lb represents a divalent aromatic hydrocarbon group or COO—,
- Lc represents a single bond, an alkylene group having at least a hydroxy group, an alkylene group having at least an aromatic group, or a divalent polycyclic aliphatic group, and when Lb is —COO—, Lc represents an alkylene group having at least an aromatic group or a divalent polycyclic aliphatic group,
- Ar represents an aromatic group, and
- R represents an aromatic group optionally having one or more substituents or a polycyclic aliphatic group optionally having one or more substituents.
