An organic optoelectronic device structure is provided that comprises the following: (a) a polymer substrate layer; (b) a first barrier region, which comprises two or more planarizing layers and two or more high-density layers, disposed over the polymer substrate layer; (c) a second barrier region, which comprises two or more planarizing layers, two or more high-density layers and at least one layer of an absorbing material that absorbs water, oxygen or both water and oxygen, disposed over the first barrier region; and (d) an organic optoelectronic device, which is selected from an organic light emitting diode, an organic electrochromic display, an organic photovoltaic device and an organic thin film transistor, disposed between the first and second barrier regions. The first and second barrier regions in this structure restrict transmission of water and oxygen from an outer environment to the optoelectronic device.
