Abstract:
1. An organic EL display comprising: lower electrodes arranged on a substrate so as to correspond to a red organic EL element, a green organic EL element and a blue organic EL element, respectively; hole injection/transport layers arranged on the lower electrodes so as to correspond to the red organic EL element, the green organic EL element and the blue organic EL element, respectively, the hole injection/transport layers having hole injection properties for hole injection, or hole transport properties for hole mobility, or both; a red organic light-emitting layer arranged on the hole injection/transport layer for the red organic EL element, and including a low-molecular material; a green organic light-emitting layer arranged on the hole injection/transport layer for the green organic EL element, and including a low-molecular material; a blue organic light-emitting layer arranged on whole surfaces of the red organic light-emitting layer, the green organic light-emitting layer and the hole injection/transport layer for the blue organic EL element; and an electron injection/transport layer and an upper electrode arranged on a whole surface of the blue light-emitting layer, the electron injection/transport layer having one or both of electron injection properties and electron transport properties, wherein,
