摘要： An organic EL device (1) includes: a first substrate (11); a second substrate (12); one or more organic EL elements; and a sealing layer (14). One surface of the first substrate (11) is a mounting surface on which the one or more organic EL elements are disposed. The first substrate (11) and the second substrate (12) are laminated in such a manner that the mounting surface of the first substrate (11) and one surface of the second substrate (12) face each other with the sealing layer (14) interposed therebetween. The second substrate (12) has at least one recessed part (16) and at least one protruding part (15) in a region inside the sealing layer (14) on the surface of the second substrate (12) facing the first substrate (11), and the moisture absorbent (19) is disposed in the recessed part (16).

摘要： The present invention provides an organic EL device that can prevent an organic EL layer(s) from being damaged when the organic EL device is bent. An organic EL device (10) of the present invention includes: a first substrate (11); a second substrate (12); one or more organic EL elements; and a sealing layer (14). Each of the one or more organic EL elements includes an organic EL layer (13) and a pair of electrodes (16, 17). One surface of the first substrate (11) is a mounting surface on which the one or more organic EL elements are disposed. The first substrate (11) and the second substrate (12) are laminated in such a manner that the mounting surface of the first substrate (11) and one surface of the second substrate (12) face each other with the sealing layer (14) interposed therebetween. The sealing layer (14) seals a gap between the first substrate (11) and the second substrate (12) along an entire periphery of a region facing the second substrate (12) on the mounting surface of the first substrate (11) and an entire periphery of a region facing the first substrate (11) on the surface of the second substrate (12) facing the first substrate (11). The organic EL device further includes one or more supporting layers (15). The supporting layers (15) are disposed in such a manner that the supporting layers (15) connect the whole or part of a region without the one or more organic EL elements on the mounting surface of the first substrate (11) and a region facing the whole or part of the region without the one or more organic EL elements on the surface of the second substrate (12) facing the first substrate (11).
