Title:
An organic light emitting element, an organic light-emitting display panel, and an organic light-emitting display
Document Type and Number:
Japanese Patent JP6111468
Kind Code:
B2
Abstract:
Each of blue light emitting elements includes: a photoanode; a translucent cathode; an organic light emitting layer between the photoanode and the translucent cathode; a first functional layer between the organic light emitting layer and the photoanode; and a second functional layer between the organic light emitting layer and the translucent cathode, and has a resonator structure. The first functional layer has an optical film thickness of 48-62 nm. The translucent cathode is a stack of a first translucent conductive layer, a metal layer, and a second translucent conductive layer stacked in this order from the second functional layer side. The first translucent conductive layer has a refractivity of 2.0-2.4, and a film thickness of 85-97 nm. The metal layer has a refractivity different by 0 to 2.0 from that of the first translucent conductive layer, and has a film thickness of 2-22 nm.
