    Abstract: A sealing layer covers more surely both of a display region and a peripheral region on a substrate. A dummy structure is formed in the peripheral region of the substrate. The dummy structure contains, for instance, at least one of the materials constituting an organic EL display structure. The dummy structure is located in the peripheral region so that the volume per unit area of the sealing layer in the peripheral region is substantially the same as that in the display region.
