An organic-inorganic hybrid composition including a polymer having a triazine ring structure in a main chain of the polymer (A);
an inorganic particulate (B); and a surface-treating agent having a triazine ring structure represented by Formula (1)(C): wherein, in Formula (1), R1 is a carboxyl group, a phosphoric acid group, a sulfo group, or a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted amino group, wherein a number median diameter (Dn50) of the inorganic particulate (B) is greater than or equal to about 1 nm and less than or equal to about 20 nm.
