ABSTRACT:
An organic electroluminescent panel, an organic electroluminescent display, an organic electroluminescent lighting device, each include an organic electroluminescent element that maintains stable light emission characteristics for a long period of time. The organic electroluminescent panel includes an element substrate; a sealing substrate facing the element substrate; and an organic electroluminescent element disposed on a sealing substrate side of the element substrate, wherein the organic electroluminescent panel further includes a first sealing member and a second sealing member, the first sealing member sealing a gap between the element substrate and the sealing substrate, the second sealing member covering the organic electroluminescent element, the first sealing member and the second sealing member being arranged with a space therebetween, the space is in a vacuum or reduced pressure state.
