Abstract: The present invention has an object of providing a light-emitting device including an OLED formed on a plastic substrate, which prevents degradation due to penetration of moisture or oxygen. On a plastic substrate, a plurality of films for preventing oxygen or moisture from penetrating into an organic light-emitting layer in the OLED (“barrier films”) and a film having a smaller stress than the barrier films (“stress relaxing film”), the film being interposed between the barrier films, are provided. Owing to a laminate structure, if a crack occurs in one of the barrier films, the other barrier film(s) can prevent moisture or oxygen from penetrating into the organic light emitting layer. The stress relaxing film, which has a smaller stress than the barrier films, is interposed between the barrier films, making it possible to reduce stress of the entire sealing film. Therefore, a crack due to stress hardly occurs.

Abstract: The object of the invention is to provide a method for fabricating a semiconductor device having a peeled layer bonded to a base material with curvature. Particularly, the object is to provide a method for fabricating a display with curvature, more specifically, a light emitting device having an OLED bonded to a base material with curvature. An external force is applied to a support originally having curvature and elasticity, and the support is bonded to a peeled layer formed over a substrate. Then, when the substrate is peeled, the support returns into the original shape by the restoring force, and the peeled layer as well is curved along the shape of the support. Finally, a transfer object originally having curvature is bonded to the peeled layer, and then a device with a desired curvature is completed.

Abstract: An inexpensive light emitting device capable of displaying a bright image and an electric appliance using the light emitting device. In the light emitting device having a pixel portion and a driver circuit formed on one insulating member, all of semiconductor elements for the pixel portion and the driver circuit are formed by n-channel semiconductor elements, thereby enabling the manufacturing process to be simplified. Each of light-emitting elements provided in the pixel portion emits light in such a direction that most of the light travels away from the insulating member, so that substantially the whole of the pixel-forming segment electrode (corresponding to a cathode of an EL element) is formed as an effective light-emitting area. Therefore, a low-priced light-emitting device capable of displaying a bright image can be obtained.
