Beschreibung
Zusammenfassung:	A photocurable adhesive composition is provided and can form an adhesive layer having good step-filling properties and durability under harsh conditions (high temperature, high humidity, thermal shock), exhibiting good properties in terms of haze, processability and adhesive strength after moist heat durability testing, and allowing reduction in permittivity. The photocurable adhesive composition includes a main component and a chain transfer agent. The main component includes a (meth)acrylic acid ester copolymer (a) having a particular structure, and the chain transfer agent is present in an amount of about 0.01 parts by weight to about 5 parts by weight relative to 100 parts by weight of the main component.
