Display apparatus

摘要

In a display apparatus including an organic EL element utilizing the optical interference effect, and a lens, a diameter of the lens is set such that, of light radiated from the organic EL element into a protective layer, light radiated at a larger angle than an angle, at which a light intensity distribution of the light radiated into the protective layer with respect to a radiation angle of the light takes a local minimum value, is not output to the outside of the display apparatus.

1. A display apparatus comprising:
an organic EL element including a first electrode, a luminescent layer, and a second electrode, the organic EL element radiating light through the second electrode; a protective layer disposed on the second electrode; and a lens disposed on the protective layer, wherein an optical distance L between a reflective surface provided by the first electrode and the luminescent layer satisfies a relationship of:
(λ0/8)×(4m+2φ/π−1)
