Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, more particularly, to a display panel and a display device. BACKGROUND

[0002] Liquid Crystal Display (LCD) is a kind of flat panel display with wide application, which has the advantages of low power consumption, miniaturization, thinness and the like. The LCD mainly realizes picture display by modulating the light field intensity of backlight source through liquid crystal switch. With the development of touch screen display technology, thinning of overall display module is the market development trend, so the touch structure develops from touch sensor external hanging type to touch sensor inlaid type, which can not only realize the thinning of touch display panel, but also greatly reduce the cost of touch screen.

[0003] In various inlaid touch display devices, the touch lines are usually in the same layer as the data lines, thereby being conducive to the thinning of the touch display panel. In order to prevent short circuit between the touch lines and the data lines adjacent to the touch lines, the spacing between the touch lines and the data lines adjacent to the touch lines needs to be set large, thereby reducing the effective light transmission area of the display panel, reducing the aperture ratio and the transmittance of the display device, and affecting the display effect. SUMMARY

[0004] Therefore, the present application provides a display panel and a display device, which are conducive to improving the effective light transmission area of the display panel and improving the display effect.

[0005] The application discloses a display panel, comprising: a first substrate and a second substrate arranged oppositely; the first substrate comprises a substrate, a first metal layer, a first electrode layer and a second electrode layer arranged on one side of the substrate; the first electrode layer is arranged on the side of the first metal layer away from the substrate; the second electrode layer is arranged on the side of the first electrode layer away from the first metal layer; the first metal layer comprises a plurality of data lines and a plurality of touch lines; the data lines and the touch lines extend along a first direction; the first electrode layer comprises a first electrode; the touch lines are electrically connected with the first electrode; the first electrode comprises a first notch; the orthographic projection of the first notch on the substrate at least partially overlaps the orthographic projection of the touch lines on the substrate; and the orthographic projection of the first notch on the substrate does not overlap the orthographic projection of the data lines on the substrate; the display panel further comprises a plurality of scan lines extending along a second direction; the scan lines and the data lines are insulated and crossed to define a plurality of first areas; wherein the first direction and the second direction intersect; a plurality of sub-pixels; the sub-pixels at least comprise a body area; the body area corresponds to the first area; and the body area is located in the first area corresponding thereto; along the second direction, two sub-pixels adjacent to one touch line are a first sub-pixel and a second sub-pixel respectively; and the touch line is located between the body area of the first sub-pixel and the body area of the second sub-pixel; the first sub-pixel comprises a first pixel electrode; the second sub-pixel comprises a second pixel electrode; the first pixel electrode and the second pixel electrode are located in the second electrode layer; along the second direction, the width of the first pixel electrode is greater than the width of the second pixel electrode.

[0006] Based on the same inventive concept, the application further discloses a display device comprising the display panel.

[0007] Compared with the prior art, the display panel and the display device provided by the application at least achieve the following beneficial effects:

[0008] The display panel provided by the application has the following advantages: along the second direction, two sub-pixels adjacent to one touch control line are a first sub-pixel and a second sub-pixel, and the touch control line is located between the body area of the first sub-pixel and the body area of the second sub-pixel. That is, along the second direction, the first sub-pixel and the second sub-pixel are located on the two sides of the same touch control line, and the touch control line and the data line are arranged between the first sub-pixel and the second sub-pixel. Since the touch control line and the data line are arranged on the first metal layer, there is a certain spacing between the touch control line and the data line arranged adjacent to each other and located between the first sub-pixel and the second sub-pixel, thereby preventing short circuit between the touch control line and the data line arranged adjacent to each other and effectively reducing the signal interference between the touch control line and the data line arranged adjacent to each other. The first sub-pixel comprises a first pixel electrode, and the second sub-pixel comprises a second pixel electrode. Along the second direction, the width of the first pixel electrode is greater than the width of the second pixel electrode. That is, in the case that the length of the first pixel electrode in the first sub-pixel remains unchanged along the first direction, the arrangement area of the first pixel electrode in the first sub-pixel can be increased, thereby being beneficial to increasing the effective light transmission area of the first sub-pixel and effectively improving the display effect.

[0009] Of course, it is not necessary for any product embodying the application to achieve all of the above-mentioned technical effects simultaneously.

[0039] Specifically, the display panel provided in the embodiment can be a liquid crystal display panel. The display panel includes a first substrate 10 and a second substrate 20 arranged oppositely. Optionally, the first substrate 10 can be understood as an array substrate, and the second substrate 20 can be understood as a color film substrate including a color resistance structure and a black matrix structure, as shown in Figure 3 The second substrate 20 includes a color resistance layer 21 and a black matrix layer 22. The color resistance layer 21 can include a plurality of color resistances of different colors, and the color resistances of different colors can be located at a plurality of opening positions of the black matrix layer 22. Alternatively, in some other optional embodiments, the first substrate 10 can be understood as an array substrate including a color resistance structure and a black matrix structure (not shown in the figure), and the second substrate 20 can be understood as a glass substrate. The embodiment is not limited in this regard. A liquid crystal layer 60 is arranged between the first substrate 10 and the second substrate 20. The liquid crystal layer 60 includes liquid crystal molecules. It can be understood that, in the embodiment, the liquid crystal molecules of the liquid crystal layer 60 are taken as positive liquid crystals for example. In some other optional embodiments, the liquid crystal molecules of the liquid crystal layer 60 can also be negative liquid crystals, which can be selected and arranged according to actual requirements. The liquid crystal molecules are parallel to the panel direction in a state without electricity, i.e., without an applied driving electric field. The angles of the positive liquid crystals and the negative liquid crystals are different. In a state with electricity, i.e., with an applied driving electric field, the long axis of the positive liquid crystal molecules deflects along the electric field direction, and the long axis of the negative liquid crystal molecules deflects perpendicular to the electric field direction. The actual requirements can be set during implementation.

[0040] The first substrate 10 of the embodiment includes at least a substrate 11, a first metal layer 12 located on the side of the substrate 11 facing the second substrate 20, and a first electrode layer 13. The first electrode layer 13 includes a first electrode 131, which can be understood as a common electrode for accessing a common voltage signal. Optionally, the first substrate 10 of the embodiment can also include a second electrode layer 14, which can be understood as a pixel electrode layer for manufacturing pixel electrodes corresponding to the sub-pixels P. The first electrode layer 13 of the embodiment is located on the side of the first metal layer 12 facing the second substrate 20, and is taken as an example for example with the second electrode layer 14 located on the side of the first electrode layer 13 facing the second substrate 20 (as Figure 3In the embodiment shown, the second electrode layer 14 can also be located on the side of the first electrode layer 13 away from the second substrate 20 (not shown in the figure), which is not limited in the embodiment.

[0041] The first metal layer 12 in the embodiment can be understood as a certain conductive metal layer in the first substrate 10, which is used to manufacture the metal conductive structure included in the display panel, for example, the first metal layer 12 includes a plurality of touch control lines TP; optionally, as shown in Figure 2 and Figure 3 As shown, the side of the substrate 11 of the first substrate 10 can also include a plurality of metal film layers, for example, a plurality of metal film layers used to manufacture thin film transistors T, and the first metal layer 12 can be understood as one of the plurality of metal film layers used to manufacture the thin film transistors T. Optionally, as shown in Figure 3 As shown, the side of the substrate 11 facing the second substrate 20 can at least include a second metal layer 15 and an active layer 16, the second metal layer 15 is used to manufacture the gate of the thin film transistor T, the scan line G of the display panel, and the active layer 16 is used to manufacture the active part of the thin film transistor T, and then the first metal layer 12 is used to manufacture the source and drain of the thin film transistor T, the data line D, and the like, that is, the touch control line TP and the data line D in the embodiment can be arranged in the same layer, and the manufacturing of the touch control line TP and the data line D in the same layer can be completed by using one mask plate process, which is beneficial to save cost, simplify the process, and at the same time, is beneficial to reduce the thickness of the display panel. It can be understood that the first substrate 10 in the embodiment can also include other metal film layers, which are not described herein, and can be understood by referring to the structure of the liquid crystal display panel in the related art.

[0042] When the display panel in the embodiment is displayed, the thin film transistor T is used as a switching device of a sub-pixel P in the display panel, and is used to transmit a pixel voltage signal to a pixel electrode in a conductive state. The gate of the thin film transistor T is connected to the scan line G of the display panel, and is connected to the scan driving circuit (not shown in the figure) through the scan line G. The source of the thin film transistor T is connected to the data line D, and is connected to the driving chip or the flexible circuit board used to provide a driving signal and bound to the display panel in sequence. The drain of the thin film transistor T is connected to the pixel electrode, and the data voltage signal is loaded to the pixel electrode through the data line D, so that the electric field for deflecting the liquid crystal molecules of the driving liquid crystal layer 60 is formed between the pixel electrode of the second electrode layer 14 and the first electrode 131 (common electrode) of the first electrode layer 13, so that the light is controlled by the deflection of the liquid crystal molecules to be emitted or not, thereby realizing the display effect of the display panel. It can be understood that the display principle of the display panel is not described herein, and can be understood by referring to the display principle of the liquid crystal display panel in the related art.

[0043] The first insulating layer 17 between the first metal layer 12 and the first electrode layer 13 in the embodiment can be understood as a planarization layer, which is used to insulate the structure of the first metal layer 12 and the structure of the first electrode layer 13, and can also play a covering role of planarizing the structure of the first metal layer 12, so as to make the first electrode layer 13 made on the first insulating layer 17 as flat as possible and ensure the display effect. When the touch line TP is made in the first metal layer 12 at the same layer as the data line D in the embodiment, a plurality of first vias 132 are formed in the first insulating layer 17, so that the first electrode 131 of the first electrode layer 13 is electrically connected with the touch line TP of the first metal layer 12 by passing through the first via 132. The first electrode 131 is reused as a touch electrode in the touch stage of the display panel, and the touch signal is transmitted through the touch line TP to realize the touch detection function. The first electrode layer 13 and the second electrode layer 14 can be formed of transparent conductive materials such as ITO (Indium Tin Oxides, Indium Tin Oxide Semiconductor Transparent Conductive Film) and the like, which are not limited in the embodiment. The first electrode 131 of the first electrode layer 13 can be a block structure, and it can be understood that the area of the block structure of the first electrode 131 can be greater than the area of a single sub-pixel P, that is, one first electrode 131 can correspond to a plurality of sub-pixels P. When the display panel performs touch detection, the block-shaped first electrode 131 and the common ground form a detection capacitor, and when a touch object such as a finger touches the display panel, the capacitance formed between the finger and the capacitor is superimposed on the first electrode 131 as a touch electrode, thereby forming a touch point coordinate to complete the detection of the touch position. It can be understood that the touch detection principle of the display panel is not described in the embodiment, and in the specific implementation, the touch principle of the in-cell touch display panel in the related art can be referred to for understanding.

[0044] It should be noted that the shapes of the pixel electrodes 40 and 50 in the drawings of the embodiment are only exemplary, and in the specific implementation, the shapes of the pixel electrodes 40 and 50 include but are not limited to the shapes, and can also be other shapes, which are not limited in the embodiment.

[0045] In the display panel provided in the embodiment, the first electrode 131 includes a first notch 1311, and the first notch 1311 at least partially overlaps the orthographic projection of the touch line TP on the substrate 11, which effectively reduces the parasitic capacitance between the first electrode 131 and the touch line TP and improves the display effect.

[0046] The display panel provided in the embodiment further includes a plurality of scan lines G extending along a second direction Y, and the data line D extends along a first direction X, and the scan line G and the data line D are insulated and crossed with each other to define a plurality of first regions 30, wherein the first direction X and the second direction Y intersect. Figure 1The schematic scan line G extends along the second direction Y, the data line D extends along the first direction X, and the first direction X and the second direction Y are perpendicular to each other. For example, the first area 30 defined by the intersection of the scan line G and the data line D can be understood as a block area. The display panel further includes a plurality of sub-pixels P, and each of the sub-pixels P includes at least a body area P10, the body area P10 corresponds to the first area 30, and the body area P10 is located in the first area 30 corresponding to the body area P10.

[0047] In the display panel provided by the embodiment, along the second direction Y, two sub-pixels P adjacent to a touch line TP are a first sub-pixel P1 and a second sub-pixel P2, and the touch line TP is located between the body area P10 of the first sub-pixel P1 and the body area P10 of the second sub-pixel P2. That is, along the second direction Y, the first sub-pixel P1 and the second sub-pixel P2 are located on the two sides of the same touch line TP, and the touch line TP and the data line D are arranged between the first sub-pixel P1 and the second sub-pixel P2. Since the touch line TP and the data line D are arranged in the first metal layer 12, there is a certain spacing between the touch line TP and the data line D arranged adjacent to each other and located between the first sub-pixel P1 and the second sub-pixel P2, thereby preventing short circuit between the touch line TP and the data line D arranged adjacent to each other, and effectively reducing the interference between the signals of the touch line TP and the data line D arranged adjacent to each other.

[0048] The first sub-pixel P1 includes a first pixel electrode 40, and the second sub-pixel P2 includes a second pixel electrode 50. Along the second direction Y, the width of the first pixel electrode 40 is greater than the width of the second pixel electrode 50. That is, in the case where the length of the first pixel electrode 40 in the first sub-pixel P1 does not change along the first direction X, the arrangement area of the first pixel electrode 40 in the first sub-pixel P1 can be increased, thereby facilitating the increase of the effective light transmission area of the first sub-pixel P1 and effectively improving the display effect.

[0049] It should be noted that the naming of the first sub-pixel P1 and the second sub-pixel P2 in the embodiment of the present application is for the purpose of clearly describing the positional relationship of each sub-pixel P, and does not specifically limit the first sub-pixel P1 and the second sub-pixel P2. In some embodiments of the present application, the sub-pixel P can be the first sub-pixel P1, and in other embodiments of the present application, the sub-pixel P can be the second sub-pixel P2, which will not be described here.

[0050] It can be understood that the structure of the display panel in the drawings of the embodiment is only an example, and in specific implementation, the structure of the display panel includes but is not limited to this, and can also include other structures capable of realizing display and touch functions. For example, the structure of the liquid crystal display panel in the related art can be understood, and the embodiment will not be described here.

[0051] Continuing to refer to Figures 1-4In some optional embodiments, the first sub-pixel P1 includes a first color resist 21a, and the second sub-pixel P2 includes a second color resist 21b, and the light transmittance of the first color resist 21a is greater than the light transmittance of the second color resist 21b.

[0052] Specifically, the first sub-pixel P1 and the second sub-pixel P2 are different in color, the first sub-pixel P1 includes a first color resist 21a, and the second sub-pixel P2 includes a second color resist 21b, and the first color resist 21a and the second color resist 21b are different in color. The second substrate 20 includes a color resist layer 21, the color resist layer 21 is located on the side of the second substrate 20 facing the first substrate 10, the first color resist 21a and the second color resist 21b are both located in the color resist layer 21, and the light transmittance of the first color resist 21a is greater than the light transmittance of the second color resist 21b. The first pixel electrode 40 in the first sub-pixel P1 has a greater setting area than the second pixel electrode 50 in the second sub-pixel P2, that is, the effective light transmittance area of the first sub-pixel P1 is greater. Since the light transmittance of the first color resist 21a is greater than the light transmittance of the second color resist 21b, the light transmittance of the display panel can be effectively increased, and the display effect can be effectively improved.

[0053] For example, the first color resist 21a can be a green color resist, and the second color resist 21b can be any one of a red color resist or a blue color resist, that is, the first sub-pixel P1 can be a green sub-pixel, and the second sub-pixel P2 can be any one of a red sub-pixel or a blue sub-pixel, which is not limited in the embodiment. Alternatively, the first color resist 21a can be a blue color resist, and the second color resist 21b can be a red color resist, that is, the first sub-pixel P1 can be a blue sub-pixel, and the second sub-pixel P2 can be a red sub-pixel, as long as the light transmittance of the first color resist 21a is less than the light transmittance of the second color resist 21b, which is not limited in the embodiment.

[0054] Continuing to refer to Figures 1-4 In some optional embodiments, the second substrate 20 includes a black matrix layer 22, the black matrix layer 22 includes a light shielding portion 221, and a projection of the touch control line TP on the substrate 11 is at least partially located in a projection of the light shielding portion 221 on the substrate 11, and a projection of the data line D on the substrate 11 is located in the projection of the light shielding portion 221 on the substrate 11.

[0055] Specifically, the second substrate 20 of the embodiment further includes a black matrix layer 22, the black matrix layer 22 includes a light shielding portion 221, and at least part of the light shielding portion 221 is located between the first color resist 211 and the second color resist 212 of the same first region 30 in a direction perpendicular to the plane on which the substrate 11 is located (it can be understood that, in order to clearly show the structure of the display panel of the embodiment, Figure 1 and Figure 2 The black matrix layer 22 is not shown in Figure 3(For understanding, please refer to the cross-sectional view). This embodiment explains that light-blocking parts 221 can be provided between color resists of different colors to block light and avoid color mixing problems between sub-pixels of different colors.

[0056] Meanwhile, the orthographic projection of the touch line TP onto the substrate 11 is at least partially located within the orthographic projection of the light-shielding part 221 onto the substrate 11, and the orthographic projection of the data line D onto the substrate 11 is located within the orthographic projection of the light-shielding part 221 onto the substrate 11. By setting the light-shielding part 221, the signal traces (including the touch line TP and the data line D) or the thin-film transistor structure in the underlying metal layer can be blocked, thus preventing the metal conductive structure from reflecting light and affecting the display quality.

[0057] Continue to refer to Figures 1-4 In some optional embodiments, the first pixel electrode 40 includes a plurality of interconnected first branches 41, and the first branches 41 are arranged along the second direction Y in the same first pixel electrode 40;

[0058] The second pixel electrode 50 includes multiple interconnected second branches 51, and the second branches 51 are arranged along the second direction Y in the same second pixel electrode 50.

[0059] The number of first branches 41 in the first pixel electrode 40 is greater than the number of second branches 51 in the second pixel electrode 50.

[0060] Specifically, the first pixel electrode 40 includes multiple first branches 41, which are arranged along the second direction Y. The first branches 41 within the same first pixel electrode 40 are electrically connected to each other, meaning each first branch 41 within the same first pixel electrode 40 is electrically connected to the drain of the same thin-film transistor T. Similarly, the second pixel electrode 50 includes multiple second branches 51, which are arranged along the second direction Y. The second branches 51 within the same second pixel electrode 50 are electrically connected to each other, meaning each second branch 51 within the same second pixel electrode 50 is electrically connected to the drain of the same thin-film transistor T. The number of first branches 41 in the first pixel electrode 40 is greater than the number of second branches 51 in the second pixel electrode 50. When the dimensions of the first branches 41 in the first pixel electrode 40 and the second branches 51 in the second pixel electrode 50 are the same, the width of the first pixel electrode 40 is greater than the width of the second pixel electrode 50 along the second direction Y. By increasing the number of first branches 41 in the first pixel electrode 40, the setting area of ​​the first pixel electrode 40 in the first sub-pixel P1 can be increased, which helps to increase the effective light-transmitting area of ​​the first sub-pixel P1 and effectively improve the display effect.

[0061] It should be noted that the number of the first branches 41 in the first pixel electrode 40 is 4 and the number of the second branches 51 in the second pixel electrode 50 is 3 in the embodiment of the present application, and in other embodiments of the present application, the number of the first branches 41 in the first pixel electrode 40 and the number of the second branches 51 in the second pixel electrode 50 can also be other values, and when the second branches 51 in the second pixel electrode 50 are commonly configured, only the number of the first branches 41 in the first pixel electrode 40 needs to be increased, and the present application does not specifically limit the number of the first branches 41 in the first pixel electrode 40 and the number of the second branches 51 in the second pixel electrode 50.

[0062] With reference to the foregoing Figures 1-4 In some optional embodiments, the first sub-pixel P1 further includes a sub-region P20, and the part of the first pixel electrode 40 located in the sub-region P20 at least partially overlaps the normal projection of the data line D on the substrate 11.

[0063] Specifically, the part of the first pixel electrode 40 located in the sub-region P20 at least partially overlaps the normal projection of the data line D on the substrate 11, that is, the part of the first pixel electrode 40 located in the sub-region P20 can be arranged in the space where the data line D is located, and without changing the arrangement of the data line D and the touch control line TP, the number of the first branches 41 in the first pixel electrode 40 can be increased, so that the arrangement area of the first pixel electrode 40 in the first sub-pixel P1 can be increased, thereby facilitating the increase of the effective light transmission area of the first sub-pixel P1 and effectively improving the display effect.

[0064] Meanwhile, since the normal projection of the first scribe 1311 on the substrate 11 does not overlap the normal projection of the data line D on the substrate 11, the first electrode 131 is arranged between the data line D and the part of the first pixel electrode 40 located in the sub-region P20, and the first electrode 131 can shield the data line D and the first pixel electrode 40, thereby effectively avoiding the interference of signals between the data line D and the first pixel electrode 40.

[0065] With reference to the foregoing Figures 1-4 In some optional embodiments, the first sub-pixel P1 further includes a first color resistance 21a, and the part of the first pixel electrode 41 located in the sub-region P20 at least partially overlaps the normal projection of the first color resistance 21a on the substrate 11.

[0066] Specifically, the first pixel electrode 40 is located at a part of the sub-area P20 in the orthographic projection of the substrate 11 and at least partially overlaps with the orthographic projection of the data line D on the substrate 11, that is, the first pixel electrode 40 is located at a part of the sub-area P20 which can reuse the space where the data line D is located and is electrically connected to the data line D. Correspondingly, the first pixel electrode 41 is located at a part of the sub-area P20 in the orthographic projection of the substrate 11 and at least partially overlaps with the orthographic projection of the first color resistance 21a on the substrate 11, that is, the first pixel electrode 40 and the first color resistance 21a are simultaneously arranged in the area corresponding to the sub-area P20 in the first sub-pixel P1, so as to realize the same light-out effect of the area corresponding to the sub-area P20 in the first sub-pixel P1 and the area corresponding to the body area P10 in the first sub-pixel P1, thereby facilitating to increase the effective light-transmitting area of the first sub-pixel P1 and effectively improve the display effect.

[0067] Figure 5 is another plan view of the display panel provided by the present application, Figure 6 is Figure 5 is an enlarged view of the E part of the display panel, Figure 7 is Figure 6 is a sectional view of the display panel along F-F', referring to Figures 5-7 In some optional embodiments, the first pixel electrode 40 includes a plurality of first branches 41 connected to each other, and the first branches 41 in the same first pixel electrode 40 are arranged along the second direction Y.

[0068] The body area P10 in the first sub-pixel P1 includes a first sub-area P11 and a second sub-area P12, the second sub-area P12 is located between the first sub-area P11 and the body area P10 in the second sub-pixel P2, and the second sub-area P12 is located between the touch control line TP and the data line D adjacent to the second sub-area P12.

[0069] In the first pixel electrode 40, part of the first branches 41 are located in the first sub-area P11, and the remaining first branches 41 are located in the second sub-area P12.

[0070] Specifically, the body region P10 in the first sub-pixel P1 includes a first sub-region P11 and a second sub-region P12, the second sub-region P12 is located between the first sub-region P11 and the body region P10 in the second sub-pixel P2, in the first pixel electrode 40, part of the first branch 41 is located in the first sub-region P11, and the remaining part of the first branch 41 is located in the second sub-region P12, that is, part of the first branch 41 in the first sub-pixel P1 is arranged between the adjacent data line D and the touch control line TP between the first sub-pixel P1 and the second sub-pixel P2, so that the distance between the adjacent data line D and the touch control line TP between the first sub-pixel P1 and the second sub-pixel P2 is large, effectively reducing the risk of short circuit between the adjacent data line D and the touch control line TP between the first sub-pixel P1 and the second sub-pixel P2. At the same time, since the light-emitting colors of the first sub-region P11 and the second sub-region P12 in the first sub-pixel P1 are the same, that is, the light-emitting colors of the first sub-region P11 and the second sub-region P12 on both sides of the touch control line TP are the same, there is no risk of color deviation when the first sub-pixel P1 is lit, so the width of the light shielding part 221 corresponding to the touch control line TP in the second direction Y can be set smaller, which is beneficial to increase the effective light transmission area of the first sub-pixel P1 and effectively improve the display effect.

[0071] With reference to Figures 5-7 In some optional embodiments, the first sub-pixel P1 further includes a first color resistance 21a, and the first color resistance 21a is partially located in the second sub-region P12.

[0072] Specifically, in the first pixel electrode 40, part of the first branch 41 is located in the first sub-region P11, and the remaining part of the first branch 41 is located in the second sub-region P12, correspondingly, part of the first color resistance 21a is located in the first sub-region P11, and part of the first color resistance 21a is located in the second sub-region P12, so that the area corresponding to the first sub-region P11 in the first sub-pixel P1 maintains the same light-emitting color as the area corresponding to the second sub-region P12 in the first sub-pixel P1, and there is no risk of color deviation when the first sub-pixel P1 is lit, so the width of the light shielding part 221 corresponding to the touch control line TP in the second direction Y can be set smaller.

[0073] Figure 8 is a plan view of still another display panel provided by the application, Figure 9 is Figure 8 is an enlarged view of the H part in the display panel, Figure 10 is Figure 9 is a sectional view of the display panel along J-J', with reference to Figures 8-10In some optional embodiments, the first sub-pixel P1 further comprises a sub-region P20, the portion of the first pixel electrode 40 located in the sub-region P20 is located between the normal projection of the touch control line TP on the substrate 11 and the normal projection of the data line D adjacent to the touch control line TP on the substrate 11 in the second direction Y.

[0074] The portion of the first pixel electrode 40 located in the sub-region P20 is located between the normal projection of the touch control line TP on the substrate 11 and the normal projection of the data line D adjacent to the touch control line TP on the substrate 11.

[0075] Specifically, the first sub-pixel P1 further comprises a sub-region P20, the portion of the first pixel electrode 40 located in the sub-region P20 is located between the normal projection of the touch control line TP on the substrate 11 and the normal projection of the data line D adjacent to the touch control line TP on the substrate 11 in the second direction Y. Since the emitting color of the body region P10 and the sub-region P20 in the first sub-pixel P1 is the same, i.e., the emitting color of the body region P10 and the sub-region P20 on the two sides of the data line D is the same, there is no risk of color deviation when the first sub-pixel P1 is lit, so the width of the light shielding part 221 corresponding to the data line D in the second direction Y can be set smaller, which is conducive to increasing the effective light transmission area of the first sub-pixel P1 and effectively improving the display effect. At the same time, the sub-region P20 of the first sub-pixel P1 is arranged between the touch control line TP and the data line D, so that the distance between the data line D and the touch control line TP adjacent to the first sub-pixel P1 and the second sub-pixel P2 is larger, effectively reducing the risk of short circuit between the data line D and the touch control line TP adjacent to the first sub-pixel P1 and the second sub-pixel P2. Moreover, arranging the sub-region P20 of the first sub-pixel P1 between the touch control line TP and the data line D is conducive to increasing the number of first branches 41 in the first pixel electrode 40, thereby increasing the arrangement area of the first pixel electrode 40 in the first sub-pixel P1, which is conducive to increasing the effective light transmission area of the first sub-pixel P1 and effectively improving the display effect.

[0076] Continuing to refer to Figures 8-10 In some optional embodiments, the first sub-pixel P1 further comprises a first color resistance 21a, and the portion of the first pixel electrode 40 located in the sub-region P20 is at least partially overlapped with the normal projection of the first color resistance 21a on the substrate 11.

[0077] Specifically, in the first pixel electrode 40, part of the first branch 41 is located in the body region P10, and the remaining part of the first branch 41 is located in the sub-region P20. Correspondingly, part of the first color resist 21a is located in the body region P10, and part of the first color resist 21a is located in the sub-region P20. Thus, the area corresponding to the body region P10 in the first sub-pixel P1 maintains the same light-emitting color as the area corresponding to the sub-region P20 in the first sub-pixel P1. When the first sub-pixel P1 is lit, there is no risk of color deviation. Thus, the width of the light-shielding part 221 corresponding to the data line D in the second direction Y can be set smaller.

[0078] Figure 11 is a plan view of still another display panel provided by the present application, Figure 12 is Figure 11 is an enlarged view of a K part of the display panel, Figure 13 is Figure 12 is a sectional view of the display panel along L-L', for reference Figures 11-13 In some optional embodiments, the first electrode 131 further includes a second notch 1312, the second notch 1312 does not overlap the normal projection of the touch control line TP on the substrate 11, and the second notch 1312 partially overlaps the normal projection of the data line D on the substrate 11.

[0079] The data line D is disconnected between the body region P10 and the sub-region P20 of the first sub-pixel P1.

[0080] The first electrode layer 13 further includes a first cross-bridge line 132, and the first cross-bridge line 132 connects the adjacent disconnected data lines D through a via hole.

[0081] The normal projection of the first cross-bridge line 132 on the substrate 11 is located in the normal projection of the second notch 1312 on the substrate.

[0082] The normal projection of the first color resist 21a on the substrate 11 partially overlaps the normal projection of the second notch 1312 on the substrate 11.

[0083] Specifically, the first electrode 131 further comprises a second notch 1312, the second notch 1312 partially overlaps the normal projection of the data line D on the substrate 11, and the data line D is disconnected between the body region P10 and the sub-region P20 of the first sub-pixel P1. Meanwhile, a first bridge line 132 is arranged in the first electrode layer 13, and the first bridge line 132 is arranged without affecting the arrangement of the first electrode 131 in the first electrode layer 13, because the normal projection of the first bridge line 132 on the substrate 11 is located in the normal projection of the second notch 1312 on the substrate. The first bridge line 132 can be connected to the adjacent disconnected data line D through a via hole, so as to realize the transmission of signals between the disconnected data lines D between the body region P10 and the sub-region P20 of the first sub-pixel P1. Since the first electrode layer 13 can be formed of a transparent conductive material, such as ITO (Indium Tin Oxides, Indium Tin Oxide transparent conductive film), etc., there is no need to arrange a light shielding part 221 to shield the area corresponding to the second notch 1312, and the first color resistance 21a can be arranged at the area corresponding to the second notch 1312, so that when the first sub-pixel P1 is lighted, the light can pass through the area corresponding to the second notch 1312, that is, it is beneficial to increase the effective light transmission area of the first sub-pixel P1 and effectively improve the display effect.

[0084] Optionally, the length of the first bridge line 132 along the first direction is less than the length of the first pixel electrode 40 along the first direction, so as to prevent the length of the first bridge line 132 from being too long and causing the impedance of the data line D to be too large.

[0085] In some optional embodiments, please refer to Figure 14 , Figure 14 is a schematic diagram of a planar structure of a display device provided by the embodiment of the present application. The display device 1000 provided by the embodiment of the present application comprises the display panel 100 provided by the above-mentioned embodiments of the present application. Figure 14 The embodiment only takes a mobile phone as an example to describe the display device 1000. It can be understood that the display device 1000 provided by the embodiment of the present application can be a computer, a television, a vehicle-mounted display device or other display devices 1000 having a display function, and the present application does not specifically limit this. The display device 1000 provided by the embodiment of the present application has the beneficial effects of the display panel 100 provided by the embodiment of the present application, and specific descriptions can be referred to the specific descriptions of the display panel 100 in the above-mentioned embodiments. The embodiment will not be described here.

[0086] It can be known from the above-mentioned embodiments that the display panel and the display device provided by the present application at least achieve the following beneficial effects:

[0087] In the display panel provided by the application, two sub-pixels adjacent to one touch control line in the second direction are a first sub-pixel and a second sub-pixel, and the touch control line is located between the body area of the first sub-pixel and the body area of the second sub-pixel. That is, in the second direction, the first sub-pixel and the second sub-pixel are located on the two sides of the same touch control line, and the touch control line and the data line are arranged between the first sub-pixel and the second sub-pixel. Since the touch control line and the data line are arranged in the first metal layer, there is a certain spacing between the touch control line and the data line arranged adjacent to each other and located between the first sub-pixel and the second sub-pixel, thereby preventing short circuit between the touch control line and the data line arranged adjacent to each other and effectively reducing the signal interference between the touch control line and the data line arranged adjacent to each other. The first sub-pixel includes a first pixel electrode, and the second sub-pixel includes a second pixel electrode. In the second direction, the width of the first pixel electrode is greater than the width of the second pixel electrode. That is, in the case that the length of the first pixel electrode in the first sub-pixel remains unchanged in the first direction, the arrangement area of the first pixel electrode in the first sub-pixel can be increased, thereby being beneficial to increasing the effective light transmission area of the first sub-pixel and effectively improving the display effect.
