Photosensitive composition, cured product, method for producing cured product, display device, touch panel, polymer, and compound

Abstract

This invention provides a photosensitive composition that yields a cured product with excellent solvent resistance while being patternable through low-temperature curing. The photosensitive composition is used to form a cured resin layer in a light-emitting device, the light-emitting device including a substrate, a light-emitting element, a sealing layer, and a cured resin portion having the cured resin layer. The photosensitive composition contains: compound (A) having a specific heterocyclic structure, the specific heterocyclic structure being at least one selected from the group consisting of an azole ring structure and a condensed ring structure of an azole ring and an aromatic ring; and a polymerization initiator. The photosensitive composition further contains a compound (C) having one or more of (meth)acrylic, oxetyl, and oxetyl groups and not having a specific heterocyclic structure, or compound (A) comprising a compound (A1) having one or more of (meth)acrylic, oxetyl, and oxetyl groups and a specific heterocyclic structure, or compound (A) comprising compound (A1) and further comprising compound (C).
