Abstract:
1. An organic EL element array comprising a plurality of organic EL elements, each said organic EL element comprising a first electrode, a first carrier-transporting layer, a light-emitting layer, a second carrier-transporting layer, and a second electrode, wherein said first carrier-transporting layer of a first organic EL element of said plurality of organic EL elements is formed in common with said first carrier-transporting layer of a second organic EL element disposed adjacent to said first organic EL element through an interpixel region, said second carrier-transporting layer of said first organic EL element is formed in common with said second carrier-transporting layer of said second organic EL element through said interpixel region, said interpixel region has a configuration such that a first electrode of said first organic EL element, said first carrier-transporting layer, a first light-emitting layer which is the light-emitting layer of said first organic EL element, a second light-emitting layer which is the light-emitting layer of said second organic EL element, said second carrier-transporting layer, and a second electrode of said first organic EL element are arranged in this order, said first light-emitting layer and said second light-emitting layer mutually are in contact with each other and overlap in said interpixel region, carrier-transporting property of one of said first light-emitting layer and said second light-emitting layer is electron-transporting property and carrier-transporting property of the other is hole-transporting property and carrier-transporting property of said first light-emitting layer is hole-transporting property when carrier-transporting property of said first carrier-transporting layer is electron-transporting property or is electron transporting property when carrier-transporting property of said first carrier-transporting layer is hole transporting property.
