The display panel in the prior art is shown in connection with fig. 1, and fig. 1 is a schematic structural diagram of the display panel in the prior art. In the prior art, a display panel 100 provided by the prior art includes a display area AA, a non-display area BB surrounding the display area AA, a substrate 00, and an insulating layer 01, a protective layer 02 and an alignment film 03 sequentially disposed on one side of the substrate 00, wherein the protective layer 02 at a position corresponding to the non-display area BB includes a groove 021, the alignment film 03 is located above the protective layer 02, and in the research process, a person skilled in the art finds that the alignment film 03 may not break at the position of the groove 021, resulting in a reason that the alignment film 03 does not break, on one hand, due to a smaller thickness of the protective layer 02 along a direction perpendicular to the substrate 00, i.e., a smaller depth of the groove 021, the alignment film 03 does not break at the position of the groove 021, and, on the other hand, due to a slower gradient of a side wall of the groove 021, the alignment film 03 does not break at the position of the groove 021, and, as the alignment film 03 enters the display panel 100 from an edge of the non-display area BB away from the display area, the edge of the non-display area BB, the water vapor enters the display panel 100, and the water vapor enters the display panel 100 at the position around the non-display area BB, resulting in abnormal.
In order to solve the above technical problems, the present application provides a display panel and a manufacturing method thereof. Embodiments of the display panel and the method for manufacturing the same provided by the present application are described in detail below.

The display panel 200 provided in this embodiment includes: a substrate base 10; an insulating layer 20, the insulating layer 20 being located on one side of the substrate base 10; a protective layer 30, the protective layer 30 being located on a side of the insulating layer 20 away from the substrate 10, the protective layer 30 comprising a first protective layer 31 and a second protective layer 32, the second protective layer 32 being located on a side of the first protective layer 31 away from the insulating layer 20; a barrier layer 40, wherein the barrier layer 40 is located between the second protective layer 32 and the first protective layer 31, and the barrier layer 40 includes a plurality of hollow areas Q; an alignment film 50, the alignment film 50 being located at a side of the protective layer 30 away from the substrate 10; the display panel further includes a display area AA and a non-display area BB surrounding the display area AA, the non-display area BB including at least one groove W where the alignment film 50 is broken; in the first direction X1, the groove W penetrates through the protective layer 30, and at least part of the groove W extends to the insulating layer 20, the groove W includes a first sub-groove W1 located in the protective layer 30 and a second sub-groove W2 located in the insulating layer 20, the first sub-groove W1 includes a first portion W11 and a second portion W12, the first portion W11 is located on a side of the barrier layer 40 away from the substrate 10, the second portion W12 is located on a side of the barrier layer 40 close to the substrate 10, the maximum size of the second portion W12 is greater than the maximum size of the first portion W11 in the second direction X2, and the hollowed-out area Q is located in the groove W; the first direction X1 is a direction perpendicular to the display panel 200, and the second direction X2 is a direction in which the non-display area BB points to the display area AA.
It will be appreciated that, in the display panel 200 provided in this embodiment, including the insulating layer 20, the protective layer 30 and the alignment film 50 sequentially disposed on one side of the substrate 10, and the groove W disposed on the non-display area BB, in order to ensure that the alignment film 50 breaks at the position of the groove W, the groove W is disposed along the first direction X1, penetrates the protective layer 30, and at least part of the groove W extends to the insulating layer 20, the groove W includes a first sub-groove W1 disposed on the protective layer 30 and a second sub-groove W2 disposed on the insulating layer 20, the first sub-groove W1 includes a first portion W11 and a second portion W12, the first portion W11 is disposed on the side of the barrier layer 40 away from the substrate 10, the second portion W12 is disposed on the side of the barrier layer 40 close to the substrate 10, and compared with the prior art in which only the groove is disposed on the protective layer 30, the depth of the groove W can be effectively increased, the alignment film 50 above the protective layer 30 may be conveniently controlled to be cut off at the groove W, and at the same time, the barrier layer 40 may be disposed between the first protective layer 31 and the second protective layer 32 while deepening the depth of the groove W, the barrier layer 40 includes a plurality of hollowed-out areas Q, and the hollowed-out areas Q are located in the groove W, i.e., extend the barrier layer 40 into the groove W, thereby further optimizing the structure of the groove W, and when the etching solution etches to the second portion W12, the barrier layer 40 causes the etching solution to etch the second protective layer 32 along the second direction X2, i.e., expands the groove width of the second portion W12, so that when the alignment film 50 is formed on the protective layer 30, the alignment film 50 flows into the groove W, on the one hand, is favorable to cut off after the alignment film 50 flows into the groove W due to deepening the depth of the groove W, on the other hand, since the barrier layer 40 extends into the groove W, and expands the groove width of the second portion W12 under the barrier layer 40, the side wall of the groove W is made to form a concave-convex structure, and meanwhile, the gradient steepness of the side wall of the groove W is increased, so that the alignment film 50 can be ensured to be disconnected at the position of the second part W12 of the groove W when flowing into the groove W, the alignment film 50 can be ensured to be disconnected at the groove W when being formed on the protective layer 30, water vapor is prevented from entering the display panel 200, the surrounding lines of the display panel 200 are prevented from being corroded, the reliability of the display panel 200 is improved, and the display effect of the display panel 200 is effectively ensured.
In some alternative embodiments, as shown in connection with fig. 2 and 5, fig. 5 is a further cross-sectional view taken in the direction N-N' of fig. 2. The display area AA in the display panel 200 provided in this embodiment includes a common electrode layer C, which is located between the first protective layer 31 and the second protective layer 32, and the barrier layer 40 and the common electrode layer C are the same layer.
The display area AA of the display panel 200 provided in this embodiment includes a common electrode layer C, and an effective electric field is formed between the common electrode layer C and the pixel electrode P by applying a common voltage to the common electrode layer C, so that a liquid crystal (not shown) is driven to rotate, and the display panel 200 displays an image. In fig. 5, the pixel electrode P is only taken as an example on the side of the common electrode C away from the substrate 10, but not limited thereto, and may be located on the side of the common electrode C close to the substrate 10, and may be specifically set according to the requirements of the actual display panel 200. The common electrode layer C is located between the first protective layer 31 and the second protective layer 32, and the first protective layer 31 and the second protective layer 32 may be used to prevent a problem of shorting the common electrode layer C with other adjacent film layers, affecting the display of the display panel 200. Since the alignment film 50 is located above the protective layer 30, the groove W is disposed at the position of the protective layer 30 corresponding to the non-display area BB, by further optimizing the structure of the groove W, the barrier layer 40 may be disposed in the film layer penetrated by the groove W, so that the groove W expands in size in the penetrated film layer, thereby increasing the possibility of the alignment film 50 being disconnected in the non-display area BB, while the common electrode layer C is located between the first protective layer 31 and the second protective layer 32, and the groove W penetrates the first protective layer 31 and the second protective layer 32, and further, the barrier layer 40 and the common electrode layer C may be disposed in the same layer, where the barrier layer 40 satisfies the condition of optimizing the groove W, and when the etching solution etches the second protective layer 32 along the second direction X2, the groove width of the second portion W12 expands, and when the alignment film 50 is formed on the protective layer 30, the alignment film 50 flows into the groove W to be disconnected, thereby preventing water vapor from entering the interior of the display panel 200 to corrode the peripheral circuit of the display panel 200, improving the reliability of the display panel 200, and effectively ensuring the display effect of the display panel 200. On the other hand, the barrier layer 40 and the common electrode layer C are arranged on the same layer, the barrier layer 40 does not need to be arranged separately, and the same process as the common electrode layer C can simplify the process of the display panel 200 and save the cost.
Alternatively, the barrier layer 40 and the common electrode layer C are made of the same material, and may be a transparent conductive material, and may be an indium tin oxide semiconductor transparent conductive material. Because the transparent conductive material is different from the material of the protective layer 30 and the insulating layer 20, the corrosion rates of the insulating layer 20, the protective layer 30 and the barrier layer 40 are different, and therefore when the etching solution etches the second portion W12, the barrier layer 40 enables the etching solution to etch the second protective layer 32 along the second direction X2, that is, expands the width of the groove of the second portion W12, optimizes the structure of the groove W, and facilitates the disconnection of the alignment film 50 at the groove W.
