In a display apparatus, second organic EL elements are closer to the edge
of a display portion than first organic EL elements. The voltage drop in
the first organic EL element is larger than that in the second organic EL
element. The thickness of the organic compound layer in the first organic
EL element is different from the thickness of the organic compound layer
in the second organic EL element. The light-extraction efficiency in the
first organic EL element is higher than the light-extraction efficiency
in the second organic EL element.
