Claim:
1. A display unit comprising: a substrate; a plurality of thin film transistors arranged on the substrate; a first insulating film arranged on the plurality of thin film transistors; and a plurality of organic light emitting elements arranged on the first insulating film, wherein the organic light emitting elements includes a first organic light emitting element, a second organic light emitting element, and a third organic light emitting element, wherein the thin film transistors includes a first transistor configured to control the first organic light emitting element, a second transistor configured to control the second organic light emitting element, and a third transistor configured to control the third organic light emitting element, wherein, in the first light emitting element, a second metal layer is arranged at a first distance from a first metal layer, and generated light is extracted through the second metal layer, wherein, in the second light emitting element, the second metal layer is arranged at a second distance from the first metal layer, and generated light is extracted through the second metal layer, wherein, in the third light emitting element, the second metal layer is arranged at a third distance from the first metal layer, and generated light is extracted through the second metal layer, wherein the first distance is larger than the second distance, wherein the second distance is larger than the third distance, and wherein the second metal layer includes ytterbium.
