Claim of US Patent No. 10,368,418

1. A display unit, comprising:a drive substrate, and
a plurality of light emitting devices provided on the drive substrate,
wherein the light emitting devices include a first light emitting device including a first electrode and a second electrode, a second light emitting device including a third electrode and the second electrode, and a third light emitting device including a fourth electrode and the second electrode,
wherein 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,
wherein an insulating film has a first opening in the first light emission region, a second opening in the second light emission region and a third opening in the third emission region,
wherein the insulating film is located between the first electrode and the second electrode, the third electrode and the second electrode and the fourth electrode and the second electrode,
wherein 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,
wherein a second angle is formed between a top surface of the second electrode and a second side surface of the insulating film in the cross sectional view,
wherein a third angle is formed between a top surface of the third electrode and a third side surface of the insulating film in the cross sectional view,
wherein the third angle is different from the first angle and the second angle, and
wherein a shape of the first opening, a shape of the second opening and a shape of the third opening are different.
