Abstract
An organic light emitting display device and a fabricating method thereof are disclosed, in which an organic light emitting diode or a cathode electrode may be prevented from being damaged by outgassing generated due to water remaining in a planarization film. The organic light emitting display device includes a substrate; a thin film transistor layer provided on the lower substrate; a planarization film provided on the thin film transistor layer to planarize the thin film transistor layer; an anode line provided on the planarization film to partially expose the planarization film in a non-display area corresponding to a periphery area of a display area; and a water absorption organic film provided on the exposed portion of the planarization film to at least partially absorb outgassing from the planarization film.
