pixel being for displaying its associated color; wherein the third pixel comprises: a first electrode; a second electrode facing the first electrode; and a light emitting member formed between the first electrode and the second electrode; wherein the light emitting-member of the third pixel has fewer light-emitting elements than the light-emitting member of the first pixel.
In some embodiments, the first electrodes of the first, second and third pixels are parts of a common electrode.
In some embodiments, each light-emitting element of the first pixel has a shorter lifetime than each light-emitting element of the second and third pixels.
In some embodiments, the light-emitting elements of the first pixel, the second pixel, and the third pixel are for respectively emitting blue, red, and green light.
In some embodiments, the at least twolight emitting elements of the first pixel comprise a first light-emitting element between the first pixel's first electrode and the charge generation layer and also comprise and a second light-emitting element between the charge generation layer and the first pixel's second electrode; the light emitting member of the first pixel further comprises an auxiliary layer formed between the first pixel's first electrode and the first light-emitting element or between the first light-emitting element and the charge generation layer or between the charge generation layer and the second light-emitting element or between the second light-emitting element and the first pixel's second electrode; the light emitting member of the second pixel further comprises an auxiliary layer formed between the second pixel's first electrode and the second pixel's one or more
