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 an anode, a cathode and an organic functional layer. The organic functional layer includes an organic light-emitting layer, a first electron transmission layer, and a hole injection layer. LUMO1 and LUMO4 satisfy: |LUMO1&#x2212;LUMO4|&#x3c;1.7 eV. HOMO5 and HOMO4 satisfy: |HOMO5&#x2212;HOMO4|&#x3c;1 eV. A work function &#x3c6;1 of the first dopant and a work function &#x3c6;4 of the cathode satisfy: &#x3c6;1&#x3c;&#x3c6;4, and a work function &#x3c6;2 of the second dopant and a work function &#x3c6;3 of the anode satisfy: &#x3c6;2&#x3e;&#x3c6;3.

Organic light-emitting display panel and display device with earth metal dopants

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.
