Light-emitting device having multi-thickness transparent conductive layers

A light-emitting device comprising:

• a first light-emitting element comprising:
• a first lower electrode;
• a first transparent conductive layer over the first lower electrode;
• an optical adjustment layer over the first transparent conductive layer;
• a first light-emitting layer over the optical adjustment layer;
• a second light-emitting layer over the first light-emitting layer;
• and
• an upper electrode over the second light-emitting layer;
• a second light-emitting element comprising:
• a second lower electrode;
• a second transparent conductive layer over the second lower electrode;
• the optical adjustment layer over the second transparent conductive layer;
• the first light-emitting layer over the optical adjustment layer;
• the second light-emitting layer over the first light-emitting layer;
• and
• the upper electrode over the second light-emitting layer;
• and
• a third light-emitting element comprising:
• a third lower electrode;
• a third transparent conductive layer over the third lower electrode;
• the second light-emitting layer over the third transparent conductive layer;
• and
• the upper electrode over the second light-emitting layer,
• wherein a thickness of the first transparent conductive layer is greater than a thickness of the second transparent conductive layer, and
• wherein the thickness of the second transparent conductive layer is substantially the same as a thickness of the third transparent conductive layer.
