as shown in fig. 1 and 4, fig. 4 is a partially enlarged structural schematic diagram of the region L in fig. 3 (for clarity, the structure of the flaring portion is illustrated by dashed lines on the black matrix 40, but it should be understood that the first light-shielding tape 401, the second light-shielding tape 402, and the flaring portion 403 are integrally formed to form the black matrix 40), and in a direction Y (only a few directions Y meeting this condition are schematically illustrated in fig. 1) in which the first non-display area NA1 points to the first display area AA1, in a specific implementation, the direction Y may be multiple, and it is only required that the direction Y points to the first display area AA1 from the first non-display area NA1, the distance between the geometric center point M of the forward projection of the first flaring portion 4031 to the second substrate 20 and the geometric center point N of the forward projection of the first support pillar 301 to the second substrate 20 is a first distance L1, and the geometric center point E of the forward projection of the second flaring portion 4032 to the second substrate 20 and the geometric center point F302 of the forward projection of the second support pillar 20 is a first distance L1, and the geometric center point F302 of the second flaring portion 4032 to the second substrate 20 The distance is a second distance L2; wherein the first distance L1 is greater than the second distance L2.

It should be noted that, in order to clearly illustrate the structure of the present embodiment, the drawings are only simple structural schematic diagrams, and the dimensional scale thereof is not taken as a reference for the technical solution of the present embodiment. Fig. 2 is a diagram illustrating an extent and a shape of the first display area AA1 on the display panel 000, and the extent and the shape of the first display area AA1 are not specifically limited in this embodiment, and may be adjusted according to a size and a pixel arrangement of the void LA of a specific product in a specific implementation, only that the first display area AA1 is disposed close to the void LA and at least partially surrounds the void LA. In order to more clearly illustrate the structures of the flaring portion 403 and the supporting post 30, fig. 3 schematically illustrates the technical solution of the present embodiment only by taking the orthographic projections of the flaring portion 403 and the supporting post 30 on the second substrate 20 as regular patterns (for example, the orthographic projections of the flaring portion 403 and the supporting post 30 on the second substrate 20 are respectively elliptical and circular in fig. 3 and 4), and the present embodiment does not specifically limit the shape of the flaring portion 403. In this embodiment, the geometric center point is regarded as a regular geometric figure when the orthographic projection of the flaring portion 403 and the supporting post 30 onto the second substrate 20 is taken as a regular geometric figure, and in practical implementation, the orthographic projection of the flaring portion 403 and the supporting post 30 onto the second substrate 20 may also be an irregular geometric figure, which is not particularly limited in this embodiment. Fig. 3 is a partial enlarged view schematically illustrating a region K in fig. 1, and fig. 4 is a partial enlarged view schematically illustrating a region L in fig. 3, it can be understood that, according to the technical solution of the present embodiment, in combination with the illustrations of fig. 1 and fig. 3, a person skilled in the art can draw an enlarged structural schematic diagram of the display panel in other regions within the range of the first display area AA1 by himself, which is not described in detail in this embodiment.
In some optional embodiments, please refer to fig. 5, fig. 5 is a schematic plane structure diagram of another display panel provided in an embodiment of the present invention (for clarity, the dual domain structure of the present embodiment is illustrated, fig. 5 does not illustrate the black matrix 40, and can be understood with reference to fig. 1 and the description of the present embodiment), and optionally, the display panel 000 of the present embodiment is a liquid crystal display panel, and the liquid crystal display panel generally includes an array substrate and a color filter substrate (corresponding to the first substrate 10 and the second substrate 20 of the present embodiment) which are oppositely disposed, wherein a plurality of color resistors defined by the black matrix are disposed on the color filter substrate, a plurality of sub-pixels defined by scan lines and data lines which are disposed in a crossing manner are disposed on the array substrate, wherein one sub-pixel corresponds to one color resistor 60 (as illustrated in fig. 1 and fig. 5, different fillings indicate color resistors of different colors), so as to realize the display of different colors. In specific implementation, the liquid crystal layer is filled between the array substrate and the color film substrate, liquid crystal molecules of the liquid crystal layer are approximately cylindrical and have a long axis and a short axis, the deflection directions of the liquid crystal molecules are different, and the optical path difference of light rays passing through the liquid crystal display panel is different, so that the viewing angle of the liquid crystal display panel has an anisotropic phenomenon. Therefore, in order to avoid the above phenomenon, those skilled in the art will design the display panel 000 to have a dual-domain structure. The principle of the double-domain structure is that two domains are arranged in the display panel and are respectively a first domain and a second domain, the rotating directions of liquid crystal molecules of the first domain and the second domain are just opposite, and the visual angles of the first domain and the second domain can be complementary in different visual angle directions, so that the visual angle problem in the horizontal direction or the vertical direction can be solved. The double-domain structure can be further classified into a true double-domain structure and a pseudo double-domain structure. The true dual-domain structure refers to that the first domain and the second domain are located in the same sub-pixel, and the pseudo dual-domain structure refers to that the first domain and the second domain are respectively located in two adjacent sub-pixels, that is, the embodiment shown in fig. 5. The true double-domain structure and the false double-domain structure can both increase the visual angle of the liquid crystal display panel and improve the color cast problem of the display panel. In a pseudo-dual-domain structure, if the first light-shielding strip 401 overlaps with the projection of the scan line of the display panel in a direction perpendicular to the light-emitting surface of the display panel 000, the second light-shielding strip 402 generally overlaps with the projection of the data line, and the extending direction of the first light-shielding strip 401 still keeps the same with the extending direction of the scan line, while the extending structure of the second light-shielding strip 402 needs to be as shown in fig. 5, i.e., the second light-shielding strip 402 extends along one direction as a whole, but due to the existence of the pseudo-dual-domain structure, the second light-shielding strip 402 is divided into a plurality of small segments, and the extending direction of each small segment is different, such that the structure of the second light-shielding strip 402 as shown in fig. 5 appears.
It should be further noted that, in the range of the first display area AA1, the farther away from the vacancy LA, the smaller the distance between the geometric center point of the forward projection of the flaring portion 403 to the second substrate 20 and the geometric center point of the forward projection of the corresponding supporting post 30 to the second substrate 20 is, the closer to the vacancy LA, the more the geometric center point of the forward projection of the flaring portion 403 to the second substrate 20 is shifted away from the vacancy LA, that is, the position of the supporting post 30 on the display panel 000 is fixed, and the farther away from the vacancy LA is realized by setting different positions of the flaring portion 403, the smaller the distance between the geometric center point of the forward projection of the flaring portion 403 to the second substrate 20 and the geometric center point of the forward projection of the corresponding supporting post 30 to the second substrate 20 is.
In some optional embodiments, please continue to refer to fig. 1, in the present embodiment, the display area AA includes a shaped edge 01, the shaped edge 01 includes a sub-edge 011, a portion of the shaped edge 01 other than the sub-edge 011 extends along the first direction X, the sub-edge 011 is recessed toward the inside of the display area AA to form an opening LA, and the first non-display area NA1 is disposed around a portion of the opening LA.
The present embodiment illustrates that the blank LA is located at an edge position of the display panel 000 and is formed by recessing the sub-edge 011 of the special-shaped edge 01 toward the inside of the display area AA, and a portion of the special-shaped edge 01 other than the sub-edge 011 extends in the first direction X (which can be understood as an extending direction of the scanning line or the data line). The position that sets up of this embodiment vacancy portion LA is similar with "bang" design, in the vacancy portion LA of this position, can place some functional modules, for example camera module, sensor module or speaker module etc to improve display device's the screen and account for than, make the display effect more outstanding.
It should be noted that the shape and the position of the hollow portion LA in the present embodiment are only schematically shown, and the design can be designed according to actual requirements in specific implementation.
