| 摘要 |
The invention provides an organic EL display device comprising a plurality of organic EL elements each having at least a first electrode, one or more organic layers participating in light emission capability, and a second electrode, the elements being able to be independently electrically operated to emit light, and a groove structure at the boundary between adjacent organic EL elements for isolating at least one of the electrodes between the adjacent organic EL elements. The organic EL display device featuring a greater proportion of light emitting region, higher reliability, a large size of substrate, a more number of elements arrayed in one substrate, and a reduced cost of manufacture is obtained as well as a method for the manufacture thereof.
