Problems solved by technology

[0003] Conventional organic light-emitting display devices include top-emission and bottom-emission structures. In the top-emission structure, the organic light-emitting device in the organic light-emitting display device has a semi-transparent cathode and a fully reflective anode. However, since the semi-transparent cathode will Produces a strong microcavity effect, resulting in a low utilization rate of outgoing light

Abstract

Embodiments of the present invention provide an organic light-emitting display panel and a display device, which relate to the technical field of organic light-emitting display, and can improve the utilization rate of emitted light under a top emission structure. The organic light-emitting display panel comprises: a cathode layer and an anode layer, the minimum transmittance of the cathode layer in the visible light band is greater than 80%; the reflectivity of the anode layer in the visible light band is greater than 90%; the cathode layer and the There is an organic material layer between the anode layers, the organic material layer includes a first electron transport layer, and the first electron transport layer is doped with a metal whose activity is higher than that of magnesium; a substrate; the substrate, the anode layer , the organic material layer and the cathode layer are sequentially arranged along the light emitting direction of the organic light emitting display panel.

Description

【Technical field】 [0001] The present invention relates to the technical field of organic light emitting display, in particular to an organic light emitting display panel and a display device. 【Background technique】 [0002] The organic light-emitting display device is also called (Organic Light-Emitting Diode, OLED) organic light-emitting diode display device. Compared with the liquid crystal display device, it has the advantages of lightness, lightness, and large viewing angle. [0003] Conventional organic light-emitting display devices include top-emission and bottom-emission structures. In the top-emission structure, the organic light-emitting device in the organic light-emitting display device has a semi-transparent cathode and a fully reflective anode. However, since the semi-transparent cathode will A strong microcavity effect is generated, resulting in a low utilization rate of outgoing light. 【Content of invention】 [0004] In view of this, embodiments of the pre...
