Zusammenfassung:	Provided is a hard coating composition that exhibits excellent extensibility, and that is capable of forming a hard coating layer that has high hardness and is transparent. The hard coating composition contains: (a) a bisphenol A-type epoxy resin having a secondary hydroxyl group and/or a bisphenol F-type epoxy resin having a secondary hydroxyl group, each having a number-average molecular weight of 900-7,000; (b) a melamine resin; (c) a photopolymerization initiator; and (d) a multifunctional (meth)acrylate monomer having at least one hydroxyl group, and/or an oligomeric compound having at least one hydroxyl group.
