Patent ID: 10516125

Abstract:
Provided are an organic light-emitting display panel and a display device. The organic light-emitting display includes an array substrate and organic light-emitting components each having anode, cathode and organic functional layer. The organic functional layer includes an organic light-emitting layer, a first and second electron transmission layer and an electron injection layer. The first electron transmission layer and electron injection layer include a first dopant containing an alkaline earth metal element or a rare earth metal element. A work function φ1 of the electron injection layer and a work function φ2 of the cathode satisfy: φ1<φ2, and the work function φ1 of the electron injection layer and a work function φ3 of the first dopant satisfy: φ1≥φ3. LUMO1 and LUMO2 satisfy: |LUMO1−LUMO2|<0.18 eV.
