A sealing structure having a barrier membrane, with which the overall thickness of a display device can be reduced while ensuring sufficient barrier properties against water and oxygen so as to prevent deterioration of luminous layers. The sealing structure includes a multi-layered resin membrane for sealing an electronic element section disposed on a substrate, which is formed by alternately depositing flattening resin layers and barrier layers on the substrate. The flattening resin layers are formed inside a blocking region surrounding the electronic element section. A display device having the sealing structure, an electronic apparatus having the display device, and a fabrication method for the display device are also disclosed.
