The insulating film 15 is used to secure insulation between the first electrode 14 and the second electrode 17, and to accurately form a desired shape of a light-emitting region in each of the organic light-emitting devices 10R, 10G and 10B. The insulating film 15 has, for example, a thickness of approximately about 600 nm, and is made of an insulating material, such as silicon dioxide (SiO2), a p
