The present invention provides a top emission type organic light emitting
display apparatus in which manufacture it is possible to prevent the
organic film from being oxidized when the upper transparent electrode is
formed, and which is capable of emitting light at a low voltage. This
organic light emitting display apparatus includes an organic light
emitting layer and an upper electrode and a lower electrode sandwiching
the said organic light emitting layer between them, and is of a structure
in which the light emitted from the organic light emitting layer is taken
out from the upper electrode side, wherein a buffer layer mostly made of
an oxide with its Gibbs free energy generated at around the melting point
being lower than -300 kJ/mol is provided between the organic light
emitting layer and the upper electrode, the side of the organic layer
which is in contact with the buffer layer being doped with an electron
donative dopant.
