| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a flexible light-emitting device which achieves both flexibility and sealability and which enables the increase in the strength of a product.SOLUTION: A flexible light-emitting device 1A comprises: a flexible light emission panel 2 having a light-emitting functional layer 15 including an organic material, and a first sealing part which seals the light-emitting functional layer 15 by a base material 11 provided on one face of the light-emitting functional layer 15 and a sealing layer 17 provided on the other face of the light-emitting functional layer 15; and a second sealing part 4A for sealing a whole peripheral edge W in the first encapsulation part, where the base material 11 and the sealing layer 17 abut each other. The second sealing part 4A includes sheet materials 20 and 30 abutting the light-emission plane 2a or a rear face 2b of the flexible light emission panel 2; openings 20a and 30a are formed in the sheet materials 20 and 30 respectively.SELECTED DRAWING: Figure 4
【課題】可撓性及び封止性を両立するとともに製品強度を向上することが可能な可撓性発光デバイスを提供する。【解決手段】可撓性発光デバイス１Ａは、有機材料を含む発光機能層１５と、発光機能層１５の一面側に設けられる基材１１及び発光機能層１５の他面側に設けられる封止層１７によって発光機能層１５を封止する第一封止部と、を有する可撓性発光パネル２と、第一封止部において基材１１及び封止層１７が互いに当接する周縁部Ｗ全体を封止する第二封止部４Ａと、を備え、第二封止部４Ａは、可撓性発光パネル２の発光面２ａ又は裏面２ｂに当接するシート材２０，３０を備え、シート材２０，３０には、開口部２０ａ，３０ａが形成されている。【選択図】 図４ |
