Abstract

A luminescent device in accordance with the present invention includes an anode, a cathode, and an organic layer containing at least one organic compound provided therebetween. The work function of the anode (Wf(anode)) and the Fermi level of the organic layer (Ef(anode)) being in contact with the anode satisfies the following equation (I): Ef(anode)− 0.2 ≦Wf(anode)≦Ef(anode)+ 0.2 [eV] (I)

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . A luminescent device comprising an anode, a cathode, and an organic layer containing at least one organic compound provided therebetween, wherein the work function of the anode (Wf(anode)) and the Fermi level of the organic layer (Ef(anode)) being in contact with the anode satisfies the following equation (I):  
       Ef(anode)−0.2≦Wf(anode)≦Ef(anode)+0.2[eV]  (I) 
     
     
         2 . A luminescent device according to  claim 1 , wherein the work function of the cathode (Wf(cathode)) and the Fermi level of the organic layer (Ef(cathode)) being in contact with the cathode satisfies the following equation (II):  
       Wf(cathode)≦Ef(cathode)[eV]  (II)
