Fig. 10 is a schematic cross-sectional view of another flexible display panel according to an embodiment of the present invention. As shown in fig. 10, the flexible display panel provided in this embodiment further includes an anode 122 electrically connected to the drain of the thin film transistor 121, a light-emitting functional layer 123 located on the anode 122, and a cathode 124 located on a side of the light-emitting functional layer 123 far from the anode 122. The present embodiment is described by taking an example in which each pixel unit 120 includes two thin film transistors 121. The number of the thin film transistors 121 of the pixel unit 120 may be one or more.

Illustratively, the material of the first hardened layer and the second hardened layer includes at least one of polyimide, polyethersulfone resin, or polyterephthalic plastic. Polyimide (PI) is one of organic polymer materials with the best comprehensive performance, and belongs to thermosetting materials, namely after the polyimide material is produced and molded, the shape of the polyimide material cannot be changed by heating, the polyimide material cannot have fluidity and can not be reshaped by heating, hydrogen bonds exist among polyimide molecules, and rigid groups such as benzene rings are contained in molecular chains and are difficult to deform, so that the polyimide material can be used for manufacturing a first hardened layer and a second hardened layer in the embodiment, and the performance of the polyimide material enables the polyimide material to well protect pixel units in a flexible display panel. The polyether sulfone (PES) resin is a high polymer material with excellent comprehensive performance, is one of a few special engineering plastics which are applied, has excellent heat resistance, physical and mechanical properties, insulating property and the like, and particularly has the outstanding advantages that the PES resin can still keep stable performance in an environment with rapid temperature change; while the poly (terephthalic acid) Plastic (PET) is a highly crystalline polymer and has excellent physical and mechanical properties in a wide temperature range, any of the above materials can be used for the first hardened layer and the second hardened layer in this embodiment, and the properties of the above materials make it possible to protect the pixel unit in the flexible display panel well.
Illustratively, the thickness of the first hardened layer is in the range of 0.5 to 20 μm. The thickness of the first hardening layer is too thick, so that the bending of the flexible display panel is not facilitated; the thickness of the first hardened layer is too thin, so that the thin film transistor in the pixel unit cannot be protected, the bending of the flexible display panel cannot be influenced by the thickness range of the first hardened layer, and meanwhile, the thin film transistor can be protected from stress damage during bending. Preferably, the thickness of the second hardened layer is the same as that of the first hardened layer, which is beneficial to maintaining the flatness of the flexible display panel, and further better protecting the thin film transistor in the pixel unit from stress damage during bending.
Based on the same concept, on the basis of the technical scheme, the embodiment of the invention also provides the flexible display. Fig. 11 is a schematic structural diagram of a flexible display according to an embodiment of the present invention, where the flexible display includes the flexible display panel 100 according to any of the embodiments. In addition, it should be noted that other components for supporting the normal operation of the display device, such as a thin film encapsulation layer, may be further included. The flexible display may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. Due to the adoption of the flexible display panel, the flexible display has the same beneficial effects as the flexible display panel.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
