Abstract

A method of manufacturing an organic light emitting display device includes providing a panel including a first opening portion formed in a first substrate and a second opening portion spaced apart from the first opening portion, disposing a transmissive-window forming composition in the second opening portion, forming an organic layer in the first opening portion, forming a metal layer on the panel so as to cover the first opening portion and the second opening portion, and forming a transmissive window by volatilizing the transmissive-window forming composition to open a region of the metal layer corresponding to the second opening portion.
