1. A display unit, comprising:
a substrate, and
a plurality of light emitting devices provided on the substrate,
the plurality of light emitting devices include at least a first light emitting device, a second light emitting device and the third light emitting device,
the first light emitting device includes a first electrode, a first part of an organic layer and a first part of a second electrode, the second light emitting device includes a third electrode, a second part of an organic layer and a second part of the second electrode, and the third light emitting device includes a fourth electrode, a third part of an organic layer and a third part of the second electrode,
the first light emitting device includes a first light emission region, the second light emitting device includes a second light emission region, and the third light emitting device includes a third light emission region,
an insulating film is disposed between the first electrode and the third electrode and between the third electrode and the fourth electrode, and the insulating film is on the substrate,
the insulating film includes a first opening corresponding to the first light emission region, a second opening corresponding to the second light emitting region and a third opening corresponding to the third light emitting region,
a first angle is formed between a top surface of the first electrode and a first side surface of the insulating film in a cross sectional view at a first point where the top surface of the first electrode contacts the insulating film,
a second angle is formed between a top surface of the third electrode and a second side surface of the insulating film in the cross sectional view at a second point where the top surface of the third electrode contacts the insulating film, and
a first distance from the first point to a first edge point of a top surface of the insulating film is different from a second distance from the second point to a second edge point of a top surface of the insulating film.
