Epoxy polymerizable compositions, and organic el device

A high refractive index of the cured product, and to provide a is the viscosity of a certain value or less with a high shear polymerizable resin composition. (A1) and S-containing epoxy resin represented by the following general formula, (A2) an epoxy compound having a 70 ° C. softening point below, (B) a curing accelerator, two or more in (C) in one molecule and a thiol compound having a thiol group, 25 ° C. as measured by a B-type viscometer, the viscosity at 60rpm to provide an epoxy polymerizable composition is 100~15000mPa · s. In the general formula, the A1 and A2, each independently represent a benzene ring or 1,3,5-triazine ring,, X11 each independently -S -, - SO2 -, - O -, - C (R21) 2 - (R21 are independently a hydrogen atom, or an alkyl group having 1 to 3 carbon atoms) indicates, Y11 and Y12 each independently represent -O- or -S-, Z1 and Z2 are each independently It indicates -O- or -S-.
