Abstract
In order to provide an organic EL panel, and a method for producing same, that makes it possible to have excellent moisture resistance and ensure sealing substrate-side transparency, provided is an organic EL panel comprising an element formation substrate () on which an organic EL element () is formed, a sealing substrate (), and a sealing layer interposed with no gaps between the element formation substrate () and the sealing substrate (), wherein: the sealing layer is constituted of an inner hygroscopic agent () covering the organic EL element (), an outer peripheral hygroscopic agent () provided along an outer peripheral edge of the inner hygroscopic agent (), and a marginal adhesive () provided along an outer peripheral edge of the outer peripheral hygroscopic agent (); the inner hygroscopic agent () is constituted of an ultraviolet curable or thermosetting gel-like resin and a desiccant added at a weight ratio of 0.3 to less than 10% to the resin; and the outer peripheral hygroscopic agent () is constituted of the aforementioned resin and a desiccant added at a weigh ratio of 10 to 80% to the resin.
