Abstract

The invention discloses a display device, a display panel and a manufacturing method thereof. The display panel includes a device layer, and further includes a first barrier layer, a buffer layer and a second barrier layer sequentially stacked on the device layer. The buffer layer includes at least two different metal organic compounds or a mixture of the at least two different metal organic compounds, wherein the at least two different metal organic compounds do not react with each other. The display panel of the present invention can improve the adhesion between adjacent layers of the packaging film, avoid peeling off of the adjacent layers of the packaging film; improve the ability to resist TFE stress, prevent the packaging film from breaking; react with multiple reactants at the same time, and improve production efficiency.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display panel and a manufacturing method thereof. Background technique [0002] Compared with the current mainstream liquid crystal display technology, OLED display technology has outstanding advantages such as high contrast, wide color gamut, flexibility, thinness, and energy saving. In recent years, OLED display technology has gradually become popular in mobile devices such as smartphones and tablets, flexible wearable devices such as smart watches, large-size curved TVs, and white lighting, and has a strong momentum of development. [0003] OLED devices have bright prospects in the display field due to their many advantages. However, the active metal used to form the metal cathode in the OLED device is very sensitive to water vapor and oxygen in the air, and it is very easy to react with the infiltrated water vapor, affecting the injection of char...
