An electronic apparatus that is presented has a substrate; an organic light-emitting device disposed on the substrate; and a thin film encapsulation portion sealing the organic light-emitting device and comprising at least one organic film. The organic film includes a cured product of a composition for forming an organic film, the composition comprising a curable material and an ultraviolet (UV) absorber. The curable material includes a (meth)acrylate compound. The organic light-emitting device includes a first electrode, a second electrode facing the first electrode, an emission layer between the first electrode and the second electrode, and a hole transport region between the first electrode and the emission layer. The emission layer includes a first compound represented by Formula 1, and the hole transport region includes a second compound represented by Formula 2:
