Problems solved by technology

However, when the flexible display device is repeatedly bent, that is, when the flexible display panel is repeatedly bent, the inorganic material insulating layer is prone to cracks or even breaks due to stress, resulting in a short circuit between the conductive film layers on both sides of the inorganic material insulating layer. and other phenomena, resulting in the degradation or even failure of the flexible display device

Abstract

The invention discloses a flexible display panel and a manufacturing method thereof and a flexible display device, and relates to the technical field of display. Quality declining and even failure ofthe flexible display device caused by cracks and even fractures of an inorganic material insulating layer because of the stress can be prevented. The flexible display panel comprises the inorganic material insulating layer. The inorganic material insulating layer comprises a non-insulating functional area. The non-insulating functional area is internally provided with removing through holes for removing the inorganic material insulating layer in the non-insulating functional area so as to remove the organic material filled in the through holes. The two sides of the non-insulating functional area are not provided with a conductive film layer contacted with the inorganic material insulating layer. The coverage area of the inorganic material insulating layer can be reduced without influencingthe insulation function of the inorganic material insulating layer, and the removing through holes are filled by using the organic material so that the probability of the cracks and even the fractures of the inorganic material insulating layer can be reduced, and quality declining and even failure of the flexible display device can be prevented.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel, a manufacturing method thereof, and a flexible display device. Background technique [0002] Since the flexible display device has characteristics such as deformability and bendability, the flexible display device has been applied more and more widely. At present, flexible display devices usually include a flexible display panel, and an insulating layer of inorganic material is usually formed in the flexible display panel to isolate the conductive film layers on both sides of the insulating layer of inorganic material, so that the gap between the conductive film layers on both sides of the insulating layer of inorganic material Insulation, for example, in an active drive organic light emitting diode (Active Matrix Organic Light EmittingDiode, AMOLED) flexible display panel, the gate insulating layer of the thin film transistor is usually an inor...
