摘要:
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.

A display apparatus includes an organic electroluminescent element, a protective layer provided in contact with the organic electroluminescent element and configured to cover the organic electroluminescent element, and a condenser lens provided in contact with the protective layer and on a light output side of the organic electroluminescent element. The condenser lens includes a convex surface having a sloping angle θS that satisfies a predetermined mathematical condition.

摘要:
An optical absorption layer having a plurality of openings corresponding to lenses is provided between a lens array and a first electrode. An edge of each of the openings is provided such that light entering in a normal direction of a substrate and traveling through an area where the corresponding lens has a maximum inclination angle is blocked.
