Abstract:
In a display apparatus including an organic EL element utilizing the optical interference effect, and a lens, a light absorbing layer is disposed 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 through the lens.
