Abstract:
An organic EL display 1 includes a sealing film 2 provided on a plastic substrate 10 to cover an organic EL element 4. The sealing film 2 includes a first sealing layer 25 on a surface of the plastic substrate 10, three stress relief layers 26, 27, and 28 on a surface of the first sealing layer 25, and a second sealing layer 29 on a surface of the stress relief layer 28. The stress relief layers 26, 27, and 28 each have a higher coefficient of thermal expansion than the first and second sealing layers 25 and 29. The stress relief layer 27 interposed between the stress relief layers 26 and 28 has a higher coefficient of thermal expansion than the stress relief layers 26 and 28.
