摘要：
An organic EL display includes: lower electrodes arranged on a substrate so as to correspond to red, green and blue organic EL elements, respectively; hole injection/transport layers arranged on the lower electrodes so as to correspond to the red, green and blue organic EL elements, respectively, the hole injection/transport layers having one or both of hole injection and hole transport properties; red and green organic light-emitting layers arranged on the hole injection/transport layers for the red and green organic EL elements, respectively, and including a low-molecular material; a blue organic light-emitting layer arranged on whole surfaces of the red and green organic light-emitting layers 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.
