Abstract
A liquid photosensitive ink composition capable of forming a cured product with a high refractive index and applicable to an inkjet method even though the photosensitive ink composition does not include the solvent, or include small amount of the solvent, a cured product of the photosensitive ink composition, a display panel having a film consisting of the cured product, and a method for producing the cured product using the above photosensitive ink composition. In a photosensitive ink composition including a photopolymerizable compound, metal compound particles, and a photopolymerization initiator, a sulfide compound having specific structure and a (meth)acrylate compound having specific structure as the photopolymerizable compound, and at least one selected from the group consisting of titanium oxide particles, barium titanate particles, cerium oxide particles, and zinc sulfide particles, as the metal compound particles are used.
