Abstract

The invention provides a display panel and a manufacturing method thereof. A display area and a bending area are defined on the display panel, the display panel comprises a flexible substrate, a firstinorganic insulating layer, a first organic insulating layer, a first metal layer, a second organic insulating layer, a second inorganic insulating layer, a second metal layer and a third organic insulating layer which are arranged in a stacking mode. The manufacturing method of the display panel comprises the following steps of: providing a flexible substrate, manufacturing a first inorganic insulating layer, manufacturing a first organic insulating layer, manufacturing a first metal layer, manufacturing a second organic insulating layer, manufacturing a second inorganic insulating layer, manufacturing a second metal layer and manufacturing a third organic insulating layer. According to the invention, the second inorganic insulating layer of the bending area is arranged on the second organic insulating layer, so that residues of the second inorganic insulating layer generated in the through holes of the first metal layer are avoided, the risk of stress concentration or film peeling generated by a first signal line under bending stress is avoided, and the product yield is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Such as figure 1 , figure 2 As shown, it is a schematic diagram of the planar structure and cross-sectional structure of the existing flexible display panel. The flexible display panel 90 includes a display area 91 and a non-display area 92. The non-display area 92 includes a peripheral area 921 surrounding the display area 91, a bending area 922 and Circuit board area 923 . The flexible display panel 90 usually adopts a soft and bendable plastic substrate, which is suitable for manufacturing narrow-frame display devices. The flexible display panel 90 designs a bending area 922 in the peripheral signal routing area, so that the signal routing area and the circuit board area 923 are folded and placed on the side or below the flexible display panel 90, thereby reducing the occupation of the non-display area 92...
