Abstract
A sealing layer covers more surely both of a display region and a peripheral region on a substrate. A dummy structure (36) is formed in the peripheral region (15) of the substrate. The dummy structure (36) contains, for instance, at least one of the materials constituting an organic EL display structure (18). The dummy structure (36) is located in the peripheral region so that the volume per unit area of the sealing layer (40) in the peripheral region (15) is substantially the same as that in the display region (13).
