    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.

    Abstract: A manufacturing method including: forming a first electrode; forming a first bank; forming a first organic functional film; forming a second bank; forming a second organic functional film; and forming a second electrode. In the forming of the second bank, the second bank is formed such that, in plan view, a bottom edge of a sidewall surface of the second bank facing the second aperture is located at the same position as or is set back from a bottom edge of a sidewall surface of the first bank facing the first aperture. In the forming of the second organic functional film, the droplet of the second ink is applied such that an upper edge of the second organic functional film within the second aperture is located at a same level as or at a higher level than the bottom edge of the sidewall surface of the second bank.

    Abstract: An organic EL element including an anode, a cathode, and a light emitting layer between the anode and the cathode. The light emitting layer includes a fluorescent material and a host material. A difference between a lowest unoccupied molecular orbital (LUMO) level of the fluorescent material and a highest occupied molecular orbital (HOMO) level of the fluorescent material is less than or equal to a difference between a LUMO level and a HOMO level of the host material. The LUMO level of the fluorescent material is equal to or higher than the LUMO level of the host material. The HOMO level of the fluorescent material is equal to or higher than the HOMO level of the host material, and a difference in energy level between the HOMO level of the fluorescent material and the HOMO level of the host material is 0.3 eV or less.
