Abstract
The present application relates to an encapsulation film, an organic electronic device comprising the same, and a method for manufacturing an organic electronic device using the same, which provides an encapsulation film having excellent reliability that allows forming a structure capable of blocking moisture or oxygen flowing into an organic electronic device from the outside, absorbs and disperses the stress according to panel bending, while preventing generation of bright spots in the organic electronic device.
Claims21
An encapsulation film comprising an encapsulation layer and a protective layer formed on the encapsulation layer and having a coefficient of thermal expansion (CTE) in a range of 6 to 30 ppm/° C., wherein
- the encapsulation layer has a strain value of less than 150% as measured, in a state laminated by laminating it to a film sample having a thickness within a range of 750 to 850 μm, after applying to the film sample a vertical force of 200 gf at 85° C. using an 8 mm aluminum parallel plate cell in the Creep mode with ARES (TA) to load the film sample, and applying a stress of 15,000 Pa to the film sample and maintaining it for 60 seconds.
