Abstract

The invention provides a display panel and a manufacturing method thereof, and a display device. The display panel includes a substrate, a film transistor layer disposed on the substrate, and a lightemitting layer disposed on the film transistor layer, wherein the light emitting layer includes a hole injection layer, a hole transport layer, an electroluminescence layer, an electron transport layer, an electron injection layer, a cathode, a covering layer and an inorganic layer which are sequentially stacked. The display panel is advantaged in that the preparation time of the inorganic layer in the light emitting layer is short, and batch production of display panels is facilitated.

Description

technical field [0001] The present application relates to a packaging technology of a display panel, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Compared with traditional LCD, OLED (Organic Light Emitting Diode, referred to as organic light-emitting diode) device has the advantages of light weight, wide viewing angle, fast response time, low temperature resistance, and high luminous efficiency, so it has been regarded as the next generation in the display industry. The new display technology, especially the OLED panel can be made into a flexible display that can be bent on a flexible substrate, which is a huge advantage of the OLED display panel. [0003] The current OLED display panel mainly includes a substrate, a thin-film transistor layer, a light-emitting layer and a thin-film packaging structure. However, the process time of vapor deposition and film formation of the light-emitting layer is very ...
