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).
Claims15
An organic EL device comprising:
- a first substrate comprising a display region and a peripheral region,
- an organic EL display structure located in the display region of the first substrate,
- a sealing layer disposed to seal the organic EL display structure and cover the display region and the peripheral region of the first substrate, and
- a second substrate fixed to the first substrate through the sealing layer,
- wherein a 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, and a space between the first and second substrates is filled with the sealing layer.
A method for manufacturing an organic EL device comprising:
- forming an organic EL display structure in a display region of a first substrate comprising the display region and a peripheral region,
- forming a dummy structure in the peripheral region of the first substrate so that the volume per unit area of the dummy structure in the peripheral region is substantially the same as the volume per unit area of the organic EL display structure in the display region,
- applying a sealing material to a second substrate, and
- bonding the second substrate to the first substrate through the sealing material so as to seal the organic EL display structure and the dummy structure and to fill a space between the first substrate and the second substrate with the sealing material.
