Patent ID: 8916856

Claim:
A display apparatus, comprising: an organic electroluminescent (EL) element of red light emission, an organic EL element of green light emission, and an organic EL element of blue light emission, the organic EL elements each at least having an anode having a metal layer, a hole transporting layer, a light emitting layer, and a cathode, the hole transporting layer disposed in common to the organic EL elements, in each respective organic EL element, an optical distance L between a light emitting position of each light emitting layer and a reflection plane of the anode satisfies following equation, (λ/8)×(−1−(2φ/π))< L <(λ/8)×(1−(2φ/π)) wherein, φ is a phase shift in the metal layer of the anode and λ is a peak wavelength of a spectrum emitted from the respective organic EL element, the light emitting layer of the organic EL element of blue light emission containing a host material and a light emitting material, a lowest unoccupied molecular orbital (LUMO) value of the hole transporting layer smaller than a LUMO value of the host material of the light emitting layer of the organic EL element of blue light emission, a value obtained by subtracting a highest occupied molecular orbital (HOMO) value of the hole transporting layer from a HOMO value of the host material of the light emitting layer of the organic EL element of blue light emission 0.5 eV or lower, a film thickness adjustment layer disposed between at least one of the light emitting layer of the organic EL element of red light emission and the light emitting layer of the organic EL element of green light emission and the hole transporting layer, a hole mobility of the film thickness adjustment layer higher than a carrier mobility of the light emitting layer of the organic EL element in which the film thickness adjustment layer is disposed, and a HOMO value of the film thickness adjustment layer equal to or lower than the HOMO value of the hole transporting layer and equal to or higher than a HOMO value of a light emitting material contained in the light emitting layer of the organic EL element in which the film thickness adjustment layer is disposed.
