Abstract: A light diffusion sheet for an organic electroluminescent element to be used in an organic electroluminescent panel. The light diffusion sheet includes: a glass fiber cloth composed of at least one glass fiber; silica on a surface of the glass fiber or between the glass fibers; and at least one selected from a group consisting of metal alkoxides and reaction products of metal alkoxides.

Abstract: Provided is an organic EL element comprising: a gas barrier layer disposed on a substrate; a light-emitting part; an inorganic sealing layer; lead-out wiring that extends outside of the inorganic sealing layer; and a sealing substrate that is bonded via a resin adhesive layer, wherein the organic EL element is configured such that above at least the lead-out wiring, the sealing substrate is folded to the substrate side and makes contact with the inorganic sealing layer, and improvement of connection reliability with external equipment is possible.
