[0046] Exemplarily, the lens layer 20 covers the pixel opening area K, but is not limited thereto.

[0047] Exemplarily, the lens layer 20 includes a first organic film layer 201 and a second organic film layer 202 which are stacked, and the first organic film layer 201 is located between the second organic film layer 202 and the base substrate 10. The first organic film layer 201 and the second organic film layer 202 are made of the same or different organic materials, for example, the first organic film layer 201 and the second organic film layer 202 are both made of organic resin materials, but not limited thereto.

[0048] Exemplarily, the first organic film layer 201 defines a plurality of basic lens structures T0 arranged in an array, wherein the basic lens structure T0 includes a basic recess T01 and a basic connecting portion T02 located around the basic recess T01; the second organic film layer 202 covers the basic recess T01 and the basic connecting portion T02 of each of the basic lens structures T0, and can continue the appearance of the plurality of basic lens structures T0, and the first organic film layer 201 and the second organic film layer 202 jointly form a plurality of the target lens structures T1.

[0049] Research has found that when a lens is patterned in the related art, the formed lens will have various uneven morphologies due to the influence of the composition process.

[0050] According to the specific structure of the above-mentioned display panel, it can be known that in the display panel provided by the embodiment of the present invention, the lens layer 20 includes a first organic film layer 201 and a second organic film layer 202 which are stacked, and the first organic film layer 201 can define a plurality of basic lens structures T0 arranged in an array, and the second organic film layer 202 covers the plurality of basic lens structures T0 and can continue the appearance of the plurality of basic lens structures T0, and the first organic film layer 201 and the second organic film layer 202 jointly form a target lens structure T1. The first organic film layer 201 can be patterned by a composition process to realize the multiple basic lens structures T0, and the second organic film layer 202 is directly covered on the first organic film layer 201 without the need for a composition process. Therefore, even if the first organic film layer 201 has various uneven morphologies on the surface after the composition process, after being covered by the second organic film layer 202, these various uneven morphologies can be flattened by the second organic film layer 202, so that the second organic film layer 202 continues the morphology of the basic lens structure T0 while ensuring that the surface of the second organic film layer 202 facing away from the base substrate 10 is smooth.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the basic lens structure T0 includes a basic concave portion T01 and a basic connecting portion T02 located around the basic concave portion T01;

[0052] The lens layer 20 also includes an angle control layer 203, and the angle control layer 203 includes a plurality of angle control graphics 203a.

The first organic film layer 201 can be patterned by a composition process to realize the multiple basic lens structures T0, and the second organic film layer 202 is directly covered on the first organic film layer 201 without the need for a composition process. Therefore, even if the first organic film layer 201 has various uneven morphologies on the surface after the composition process, after being covered by the second organic film layer 202, these various uneven morphologies can be flattened by the second organic film layer 202, so that the second organic film layer 202 continues the morphology of the basic lens structure T0 while ensuring that the surface of the second organic film layer 202 facing away from the base substrate 10 is smooth. In this way, when the anode layer 30, the light-emitting functional layer 40 and the cathode layer 50 are subsequently formed, the anode layer 30, the light-emitting functional layer 40 and the cathode layer 50 will not be pierced by the various uneven morphologies, thereby avoiding the occurrence of undesirable phenomena such as the aggregation of short-type dark spots on the display panel.
