Problems solved by technology
However, the flatness of the part near the edge of the opening area of the luminescent layer is often poor. Although the circular arc transition method is used to try to improve its flatness, the luminous brightness of the part near the edge of the luminescent layer is still not high. Uniformity, which will adversely affect the display effect of OLED products
[0006] Therefore, there is a need for a flexible display panel to overcome the problems of film layer failure and shedding, and the uneven brightness of the flexible display panel

The invention provides a flexible display panel and a preparation method thereof. The flexible display panel comprises a base layer, a pixel definition layer, a light-emitting layer and a cathode layer. The pixel definition layer is arranged on the base layer, the pixel definition layer is provided with a plurality of opening areas and a plurality of spacer areas, the opening areas are used for limiting light-emitting areas of sub-pixels respectively, and the spacer areas are located between every two adjacent opening areas respectively; the light-emitting layer is arranged in the opening areas; the cathode layer is arranged on the light-emitting layer. The spacer areas are in an inverted trapezoid shape, and the light-emitting layer and the cathode layer can be disconnected from the corresponding spacer areas to form gaps. When the flexible display panel is bent, the gap can release stress generated during bending, and the problems of failure and falling of a film layer are solved.
Description
technical field [0001] The present application relates to the technical field of display panels, in particular to a flexible display panel and a preparation method thereof, which can prevent film failure or peeling off. Background technique [0002] Flexible display panels generally have a multi-layer film structure. Due to the influence of the physical properties of each film layer, when the flexible display panel is bent, the difference in deformation stress between the layers is likely to cause the film layer to fail and fall off. [0003] Please refer to figure 1 as shown, figure 1 It is a structural diagram of a flexible display panel in the prior art. A pixel definition layer 91 and a spacer layer 92 located on the pixel definition layer 91 are formed on the base layer 90 of the flexible display panel 9. The pixel definition layer 91 is formed with a plurality of opening areas 911 , each opening area 911 exposes the anode layer 93 , and then in each opening area 911...
