The application provides a display panel which can be used for various display modes, such as OLED display, quantum dot display, Micro-LED display and the like. Here, the OLED display is taken as an example for explanation, but is not limited to this display mode.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present application. In this embodiment, the display panel includes a substrate 10, a light emitting layer 101, and at least one mixed film layer 20, the light emitting layer 101 is disposed on a surface of one side of the substrate 10, the mixed film layer 20 is located on a side of the light emitting layer 101 away from the substrate 10, the mixed film layer 20 includes a patterned first functional film layer 201 and a second functional film layer 202 located in a vacant position of the patterned first functional film layer 201, that is, the first functional layer 201 and the second functional layer 202 are disposed in the same layer; the first functional film layer 201 includes an anti-reflective material and/or an elastic material, and the elastic material includes an organic material having an elastic modulus lower than a predetermined value, such as an organic material having an elastic modulus lower than 5MPa, preferably an organic material having an elastic modulus of 2 to 4MPa, and for convenience of description, the organic material having an elastic modulus lower than the predetermined value is referred to as a super-elastic modulus material.
Generally speaking, an elastomer undergoes a change in shape (called "strain") upon application of an external action, and the "elastic modulus" is generally defined as: the stress in the unidirectional stress state is divided by the strain in that direction. In the elastic deformation stage of the material, the stress and the strain are in a proportional relation (namely, the material conforms to Hooke's law), and the proportionality coefficient of the material is called elastic modulus. "elastic modulus" is a physical quantity describing the elasticity of a substance, and is a general term indicating that the method may be "young's modulus", "bulk modulus", or the like. For flexible display panel products, the bending strength should not be too great, e.g. reducing the thickness of the product as much as possible to reduce the bending strength, or reducing the stiffness of the material to reduce the bending strength. However, if the thickness or the elastic modulus is too small, the local strain will be large under the action of external force, which easily causes the device to be damaged and cannot protect the device better; when the elastic modulus is too high, especially when a material with a high elastic modulus is used at a position away from the neutral plane, the bending strength is increased, so that the display panel product is difficult to bend, and the film layer is easy to break or separate due to too high strain.
With the implementation of the embodiment, the elastic material has certain elasticity and bending resistance; the antireflective material can reduce reflection of ambient light. Through setting up antireflection rete and/or elasticity rete, can improve this display panel's resistant bending property and/or can reduce its reflection to external light.

The first functional film block is formed by patterning, so that the bending stress of the first functional layer can be released, the bending resistance is improved, the directionality of the released stress can be increased by arranging the first functional film block in a mode of reversing the size of the first functional film block, and the first functional film block is suitable for bending in various directions and angles, such as inner bending, outer bending and the like.

I.e. the first functional layer is arranged above the pixel defining area and the second functional layer is arranged above the display device. In this case, the first functional layer may be a transparent material or a non-transparent material, and the display effect can be prevented from being affected by the introduction of the antireflection material by implementing this embodiment mode.
In one embodiment, the non-light-emitting region is a black matrix, and the non-light-emitting region is configured to absorb light incident on the non-light-emitting region and reduce reflection by directly preparing a pixel defining layer using a black organic material, or by coating a black film layer on the pixel defining layer.
