Abstract: To provide an organic electroluminescent element that can attain efficiency improvement by forming an electron injection layer by a film that is stable and excellent in uniformity, and forming a charge generation layer capable of effectively exhibiting the function. In an organic electroluminescent element provided with at least one organic layer between a pair of electrodes, an electron injection layer comprising a ZnO-containing layer, and a charge generation layer containing an electron acceptor-containing film in contact with the cathode side thereof and an electron donor-containing film adjacent thereto are formed.

Abstract: A grommet is disclosed, which grommet comprises a female member of a U-shaped end face containing a U groove for accommodating a stretched cord and provided at one extremity of said U groove with an elevated wall rising from the bottom of said groove and at the other extremity with a projecting wall extending inwardly from one side wall and a male member adapted to fit the U groove of the female member for fast engagement therewith, whereby the engagement of the male and female members gives rise to a laterally elongate opening on the side incorporating said elevated wall and a longitudinally elongate opening on the side incorporating the projecting wall. When the male and female members are brought into mutual engagement with a cord interposed therebetween, the cord is fastened in position in its twisted state within the grommet.
