Abstract

The invention relates to a display panel, a display device and a manufacturing method of the display panel. The display panel comprises an underlying substrate, an OLED device layer and a thin film packaging layer which are sequentially stacked. The thin film packaging layer comprises a first inorganic packaging layer, an organic packaging layer and a second inorganic packaging layer which are stacked in sequence, wherein the first inorganic packaging layer and / or the second inorganic packaging layer are / is provided with a nanotube layer extending into the organic layer on the contact surface with the organic packaging layer. The beneficial effects are that: according to the display panel,the nanotube layer is arranged in that organic packaging layer, the capillary action is utilized tomake the first inorganic packaging layer or the second inorganic packaging layer or the combination between the first inorganic packaging layer and the second inorganic packaging layer and the organic packaging layer more tightly so that the contact area of the display panel is increased, the display panel is not liable to detach when the display panel is bent or subjected to transverse pressure,the internal film layer is better protected from external water, oxygen, impurities and the like and the quality of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel, a display device and a method for manufacturing the display panel. Background technique [0002] The development of OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology is advancing by leaps and bounds. OLED products have received more and more attention and applications due to their advantages of lightness, lightness, fast response, wide viewing angle, high contrast, and bendability. In display fields such as mobile phones, tablets, and TVs. With the continuous development of technology, flexible and foldable display panels have become an inevitable development trend. [0003] Existing display panels must pass the bending test if they want to realize the folding function. However, during the bending process, the organic layer and the inorganic layer of the packaging structure are prone to separation, which makes the external water, ...
