referring to fig. 6, the curved display panel 100 further includes a black matrix 30 extending along the second direction, and a front projection of the black matrix 30 on the surface of the curved display panel 100 does not overlap with a front projection of the third electrode subunit 213(223) of each first subpixel electrode on the surface of the curved display panel 100.
Specifically, referring to fig. 2, the curved display panel 100 provided in the embodiment of the present application includes a plurality of sub-pixels 10 arranged in an array along a first direction and a second direction, and a connecting line of centers of the sub-pixels arranged along the first direction in a plane where the curved display panel 100 is located is an arc line; referring to fig. 3, two kinds of pixel electrodes 20, one is a first sub-pixel electrode 21 and the other is a second sub-pixel electrode 22, are disposed in each sub-pixel 10, and the first sub-pixel electrode 21 and the plurality of second sub-pixel electrodes 22 are sequentially arranged along a first direction; referring to fig. 4 and 7, the first subpixel electrode 21 in the embodiment of the present application includes a first electrode subunit 211, a second electrode subunit 212, and a third electrode subunit 213, and the first electrode portion 23 and the second electrode portion 24 in the third electrode subunit 213 are connected to the first electrode subunit 211 and the second electrode subunit 212, respectively. Referring to fig. 5, the second sub-pixel electrode 22 in the embodiment of the present application also includes a first electrode sub-unit 221, a second electrode sub-unit 222, and a third electrode sub-unit 223, and a first electrode portion 27 and a second electrode portion 28 in the third electrode sub-unit 223 are respectively connected to the first electrode sub-unit 221 and the second electrode sub-unit 222; the extending directions of the first electrode part 27 and the second electrode part 28 of the second sub-pixel electrode 22 form an included angle smaller than 180 degrees; with continued reference to fig. 3 and fig. 5, in the same sub-pixel 10, the first sub-pixel electrode 21 is disposed away from an angle formed by the extending directions of the first electrode portion 27 and the second electrode portion 28 of the second sub-pixel electrode 22. In particular, referring to fig. 6, the front projection of the black matrix 30 extending along the second direction in the curved display panel 100 on the surface of the display panel 100 does not overlap the front projection of the third sub-electrode unit 213 of the first sub-pixel electrode 21 on the surface of the display panel 100, and since the liquid crystal in the curved display panel 100 rotates under the driving action of the electric field generated between the pixel electrode 20 and the common electrode corresponding to each sub-pixel 10 to transmit light, the larger the electric field intensity, the larger the liquid crystal rotation amplitude, the more light is transmitted. In the prior art, because the black matrix is overlapped with the sub-pixel electrode positioned at the leftmost side, an electric field generated in a corresponding area of the black matrix is stronger, the deflection intensity of liquid crystal is higher, light rays transmitted between adjacent sub-pixels are more, and the risk of light leakage between the adjacent sub-pixels is higher. In the embodiment of the present invention, when the orthographic projections of the black matrix 30 and the third sub-electrode unit 213 on the surface of the display panel 100 are not overlapped, the electric field intensity generated in the area corresponding to the black matrix 30 is weak, that is, the electric field intensity generated in the area between the adjacent sub-pixels is weak, and when the electric field intensity is weak, the liquid crystal deflection amplitude is also reduced, even if the curved display panel has the misalignment, the light transmitted between the adjacent sub-pixels is correspondingly reduced, that is, the light transmitted between the adjacent sub-pixels is also very little, therefore, compared with the prior art in which the middle area of the pixel electrode is overlapped with the black matrix, the curved display panel 100 provided in the embodiment of the present invention can effectively reduce the phenomenon of light leakage between the adjacent sub-pixels 10 in the first direction and causing color mixing even if the misalignment occurs during the misalignment, the risk of color cast of the curved display panel 100 in the picture display process is reduced, and therefore the display effect of the curved display panel 100 and the visual experience effect of a user are improved.
It should be noted that fig. 2 is only a top view of the curved display panel 100 provided in the embodiment of the present application, in actual situations, the sizes of the sub-pixels 10 in the top view are not completely equal, the sizes of the sub-pixels in the top view are only schematic and do not represent actual dimensions, fig. 2 only schematically shows one bending form of the curved display panel, and actually, the curved display panel may also be bent in other forms, which is not specifically limited in the present application. In addition, in the embodiments shown in fig. 3 to fig. 6, the drawings are only schematic partial structures of the pixel electrode, the first subpixel electrode, or the second subpixel electrode, and do not show a complete electrode structure or a complete subpixel structure, and the complete electrode structure will be described later.

According to the embodiments, the application has the following beneficial effects:
in the curved-surface display panel and the display device provided by the application, two pixel electrodes are arranged in each sub-pixel, one is a first sub-pixel electrode, the other is a second sub-pixel electrode, the first sub-pixel electrode and the plurality of second sub-pixel electrodes are sequentially arranged along a first direction and respectively comprise a first electrode sub-unit, a second electrode sub-unit and a third electrode sub-unit, and a first electrode part and a second electrode part in the third electrode sub-unit are respectively connected with the first electrode sub-unit and the second electrode sub-unit; an included angle smaller than 180 degrees is formed between the extending directions of the first electrode part and the second electrode part of the second sub-pixel electrode, and the first sub-pixel electrode deviates from the included angle in the same sub-pixel. Particularly, the orthographic projection of the black matrix extending along the second direction in the curved display panel on the surface of the display panel is not overlapped with the orthographic projection of each third sub-electrode unit on the surface of the display panel, because the liquid crystal in the curved display panel rotates under the driving action of the electric field generated between the pixel electrode and the common electrode corresponding to each sub-pixel so as to realize light transmission, when the orthographic projection of the black matrix and the orthographic projection of the third sub-electrode unit on the surface of the display panel are not overlapped, the electric field intensity generated in the area corresponding to the black matrix is weaker, namely, the electric field intensity generated in the area between the adjacent sub-pixels is weaker, the deflection amplitude of the liquid crystal is reduced, even if the alignment deviation occurs, the light transmitted between the adjacent sub-pixels is correspondingly reduced, namely, the light transmitted between the adjacent sub-pixels is less, therefore, the phenomenon that light leakage occurs between sub-pixels adjacent to each other in the first direction to cause color mixing is effectively reduced, the risk that color cast occurs in the picture display process of the display panel is reduced, and therefore the display effect of the display panel and the visual experience effect of a user are favorably improved.
