摘要： PROBLEM TO BE SOLVED: To obtain a luminescence-assisting agent for an organoelectroluminescent element which improves luminescence efficiencies and luminescence life without substantially changing desirable luminescence characteristics of a guest compound in the organoelectroluminescent element where a host compound and the guest compound are used in combination, and to provide its use. SOLUTION: In the organoelectroluminescent element, a coumarin derivative having a julolidine skeleton and a phenanthrothiazole skeleton and represented by formula 1 is employed as the luminescence-assisting agent for the organoelectroluminescent element. A display panel and an information display device are obtained by using the organoelectroluminescent element. In formula 1, R 1 -R 5 are each independently hydrogen atom or a hydrocarbyl group, provided that the hydrocarbyl group can bear a substituent group; and R 6 -R 13 are each independently hydrogen atom or a substituent group.

摘要： PROBLEM TO BE SOLVED: To eliminate the inconvenience caused by formation of a transparent electrode of metal oxide by eliminating the necessity to form the transparent electrode of the metal oxide of ITO or the like requiring a high temperature annealing to give a harmful effect on an organic layer at a negative electrode in an organic EL element of a top emission type. SOLUTION: As for the organic EL element 10, a positive electrode 12, the organic layer 13 including the light-emitting layer 17, and the negative electrode 14 are consecutively laminated on the substrate 11, and light emission of the light-emitting layer 17 is taken out from the opposite side of the substrate 11. The negative electrode 14 is constituted of an electron injection layer 18 transparently formed by calcium of alkaline earth metal, and a covered layer 19 which covers the other side face of a face opposed to the organic layer 13 of the electron injection layer 18, and which is transparently formed by the metal (silver) to play a role to protect the electron injection layer 18. Then, this is formed so that resistance value of the negative electrode 14 becomes the resistance value or less of the transparent electrode made of the ITO (indium tin oxide) which is formed in the same shape as the negative electrode 14 and at the same position.
