[0032] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the scope of protection of the present application.
[0033] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but a person skilled in the art can realize the application of other processes and / or the use of other materials.
[0034] Please refer to FIG. 1, FIG. 2 and FIG. 3, the liquid crystal display panel includes a data line 1, a pixel electrode 2 arranged above the data line 1, and a common electrode 3 arranged on the side of the pixel electrode 2 away from the data line 1. After the pixel electrode 2 and the common electrode 3 are powered on, an electric field can be formed to cause the liquid crystal between the pixel electrode 2 and the common electrode 3 to deflect. However, when the data line 1 is loaded with a voltage, an electric field can be formed between the data line 1 and the oppositely arranged common electrode 3, which in turn causes the liquid crystal around the data line 1 to deflect, resulting in a light leakage phenomenon, and the data line 1 also causes crosstalk to the signal on the adjacent pixel electrode 2. At present, a transparent electrode is usually formed as a shielding electrode 4 on the data line 1, and a common voltage signal is loaded on the shielding electrode 4 to improve the light leakage and crosstalk phenomena caused by the data line 1. However, since only an insulating layer 5 of a certain thickness is arranged between the shielding electrode 4 and the data line 1 in the non-display area NA on the side of the display area, the static electricity accumulated in the shielding electrode 4 and the data line 1 during the process is likely to break through the insulating layer 5 between the shielding electrode 4 and the data line 1, which in turn causes the shielding electrode 4 and the data line 1 to be short-circuited, resulting in a dark line phenomenon on the display panel.
[0035] Please refer to FIG. 4 and FIG. 5, the embodiment of the present application provides a display panel, which includes a display area 101 and a non-display area 102 adjacent to the display area 101, and further includes a substrate, a first metal layer 10, a first insulating layer 41 and a second metal layer 30.
[0036] The first metal layer 10 is arranged on the substrate, and includes a plurality of data lines 11. The data lines 11 are arranged in the display area 101 and extend to the non-display area 102.

[0042] In an embodiment of the application, a plurality of data lines extend along a first direction and are arranged along a second direction, the first direction and the second direction intersect, and the spacer comprises a plurality of first color resist arranged along the second direction.
[0043] One of the first color resist is located between two adjacent first line segments and extends to the adjacent first line segment along the second direction, and two adjacent first color resist are connected to cover the first line segment between the two adjacent first color resist.
[0044] In an embodiment of the application, the orthogonal projections of two adjacent first color resist on the substrate are connected or partially overlap.
[0045] In an embodiment of the application, the display area comprises a plurality of pixel areas arranged along the first direction and the second direction, and the display color resist comprises a plurality of second color resist arranged along the second direction, and one of the second color resist covers a plurality of pixel areas arranged along the first direction.
[0046] One of the second color resist is connected with one of the first color resist along the first direction, and the color of the connected first color resist and second color resist is the same, and the color of the adjacent second color resist is different.
[0047] In an embodiment of the present application, the spacer part comprises one of a first color resist, a second color resist and a third color resist, and the colors of the first color resist, the second color resist and the third color resist are different from each other.
[0048] Alternatively, the spacer part comprises a stacked structure of at least two of the first color resist, the second color resist and the third color resist.
[0049] In an embodiment of the present application, the display area comprises a plurality of pixel areas arranged along a first direction and a second direction, and the first direction intersects the second direction.
[0050] The display color resist comprises a plurality of the first color resist, a plurality of the second color resist and a plurality of the third color resist arranged in the plurality of pixel areas, and one of the first color resist, the second color resist and the third color resist is arranged in one of the pixel areas.
[0051] In an embodiment of the present application, the display panel further comprises a third metal layer arranged between the substrate and the first metal layer, and the third metal layer comprises a signal line arranged in the non-display area, and in the non-display area, the shielding electrode is connected with the signal line through the color resist layer.
[0052] In an embodiment of the present application, the data line extends to the non-display area along the first direction, and the non-display area comprises a first sub-area and a second sub-area located on opposite sides of the display area along the first direction, and the spacer part is arranged in the first sub-area and / or the second sub-area.
[0053] Specifically, please continue to refer to FIG. 4 and FIG. 5, the display panel further comprises a color resist layer 20 arranged between the first insulating layer 41 and the second metal layer 30, and an interlayer dielectric layer 42 arranged on a side of the second metal layer 30 away from the color resist layer 20.
[0054] In some embodiments, the display panel further comprises an array substrate and an opposite substrate arranged oppositely, and a liquid crystal layer between the array substrate and the opposite substrate; the array substrate comprises the first metal layer 10, the color resist layer 20 and the second metal layer 30.
[0055] Further, the display area 101 includes a plurality of pixel areas 1011, and the array substrate includes a substrate, a thin film transistor layer disposed on the substrate, and a pixel electrode disposed in each of the pixel areas 1011, and the thin film transistor layer includes a plurality of thin film transistors; for example, the first metal layer 10 can further include a source and a drain of the thin film transistor, one of the source and the drain is connected to the data line 11, and the data line 11 is used to transmit a data signal to the source or the drain, and the other of the source and the drain is connected to the pixel electrode and transmits the data signal to the pixel electrode to control the deflection of liquid crystal molecules in the liquid crystal layer.
[0056] It should be noted that the electric field generated by the data line 11 is easy to cause the liquid crystal molecules in the liquid crystal layer to produce deflection other than the preset, resulting in light leakage phenomenon; in addition, the signal in the data line 11 is also easy to cause crosstalk to the signal in the pixel electrode, which will also affect the display effect of the display panel.
[0057] Therefore, the display panel provided by the embodiment of the present application further includes a second metal layer 30 located above the first metal layer 10, and the second metal layer 30 includes a shielding electrode 31, the shielding electrode 31 can cover the display area 101 and extend into the non-display area 102, and the shielding electrode 31 can be prepared by using a transparent conductive material, so as not to affect the light output of the display panel.
[0058] It can be understood that in the display area 101, the orthogonal projection of the data line 11 on the substrate is located in the orthogonal projection of the shielding electrode 31 on the substrate, and thus the shielding electrode 31 can shield the signal in the data line 11, which can avoid the electric field generated by the data line 11 and the electrode on the opposite substrate to affect the deflection of the liquid crystal molecules, and can also improve the crosstalk of the signal in the data line 11 to the signal in the pixel electrode.
[0059] In some embodiments, the material of the shielding electrode 31 can include ITO material, and the shielding electrode 31 can be loaded with a common voltage signal.
[0060] In some embodiments, the plurality of data lines 11 extend along a first direction M and are arranged along a second direction N, and the first direction M and the second direction N intersect; preferably, the first direction M and the second direction N overlap. It should be noted that the data line 11 is arranged in the display area 101 and extends along the first direction M into the non-display area 102; and the shielding electrode 31 also partially extends into the non-display area 102, so that in the non-display area 102, the data line 11 and the shielding electrode 31 partially overlap in the thickness direction of the display panel. Since the data line 11 and the shielding electrode 31 can both accumulate static electricity during the process of the display panel, the first insulating layer 41 in the data line 11 and the shielding electrode 31 is easily broken down by static electricity, resulting in short circuit between the data line 11 and the shielding electrode 31, and thus causing the display panel to have display unevenness such as dark lines.
[0061] In the embodiments of the present application, the spacer 21 is additionally arranged between the overlapping first metal layer 10 and the second metal layer 30, and the spacer 21 is located between the first insulating layer 41 and the second metal layer 30, i.e. the spacer 21 is also located between the data line 11 and the shielding electrode 31, and simultaneously located between the first insulating layer 41 and the shielding electrode 31, and located on the side of the first insulating layer 41 away from the data line 11. On the one hand, the distance between the data line 11 and the shielding electrode 31 can be increased, and on the other hand, the thickness of the film layer spacing between the data line 11 and the shielding electrode 31 can be increased, so that the probability of the film layer spacing between the data line 11 and the shielding electrode 31 being broken down by static electricity can be effectively reduced, the probability of short circuit between the data line 11 and the shielding electrode 31 can be reduced, and the display uniformity of the display panel can be improved.
[0062] In some embodiments, the color resistance layer 20 includes the spacer 21 arranged in the non-display area 101, and in the non-display area 102, the spacer 21 is arranged between the overlapping data line 11 and shielding electrode 31. In the embodiments of the present application, the color resistance layer 20 is used to prepare the spacer 21 in the non-display area 101, so that no additional film layer needs to be added, the process procedure can be saved, and the process cost can be reduced.
[0063] It should be noted that the display panel provided in the embodiments of the present application can be a COA type (Color Filter On Array) display panel, i.e. the color resistance layer 20 is arranged on the array substrate.
[0064] Further, the data line 11 includes a first line segment 111 extending into the non-display region 102 and overlapping with the shielding electrode 31, a projection of the first line segment 111 on the substrate is located within a projection of the spacer 21 on the substrate, and the projection of the spacer 21 on the substrate at least partially overlaps with a projection of the shielding electrode 31 on the substrate within the non-display region 102.
[0065] In some embodiments, the data line 11 extends in the first direction M by a distance greater than a distance by which the shielding electrode 31 extends in the first direction M within the non-display region 102, and therefore, the spacer 21 needs to extend in the first direction M by a distance greater than or equal to a distance by which the shielding electrode 31 extends in the first direction M within the non-display region 102, so that the spacer 21 is arranged between the data line 11 and the shielding electrode 31 overlapping with each other within the non-display region 102.
[0066] In some embodiments, within the non-display region 102, a projection of the shielding electrode 31 on the substrate overlaps with a projection of the spacer 21 on the substrate, or the projection of the shielding electrode 31 on the substrate is located within a coverage range of the projection of the spacer 21 on the substrate.
[0067] In some embodiments, the data line 11 extends in the first direction M to the non-display region 102, the non-display region 102 includes a first sub-region 1021 and a second sub-region 1022 located on opposite sides of the display region 101 in the first direction M, the spacer 21 is arranged in the first sub-region 1021 and / or the second sub-region 1022, and the embodiments provided in the drawings of the present application take the data line 11 extending in the first direction M to the first sub-region 1021 and the second sub-region 1022 and the data line 11 being located in the first sub-region 1021 and the second sub-region 1022 as examples for description.

[0069] In some embodiments, the third metal layer 50 can further comprise a scan line, a common voltage signal line and a gate of the thin film transistor.
[0070] In an embodiment of the present application, referring to FIG. 4, FIG. 5 and FIG. 6, the separation pad 21 comprises a plurality of first color resists 211 arranged along the second direction N, and the plurality of first color resists 211 are connected to cover the plurality of first line segments 111.

[0072] In some embodiments, the first line segment 111 between two adjacent first color resists 211 can also be covered by any one of the two adjacent first color resists 211.
[0073] In some embodiments, the orthographic projections of two adjacent first color resists 211 on the substrate 43 are connected, as shown in FIG. 8.
[0074] In some embodiments, the orthographic projections of two adjacent first color resists 211 on the substrate 43 overlap, as shown in FIG. 9.
[0075] In some embodiments, the first color resist 211 can be selected from at least one of a red color resist, a green color resist and a blue color resist.
[0076] Further, in some embodiments, please refer to FIG. 4, FIG. 5, FIG. 6, FIG. 10 and FIG. 11, the display area 101 comprises a plurality of pixel areas 1011 arranged along the first direction M and the second direction N, and the pixel area 1011 is provided with a thin film transistor and a pixel electrode, and a data signal can be transmitted to the thin film transistor and the pixel electrode through the data line 11.
[0077] The color resistance layer 20 comprises a display color resistance 22 arranged in the display area 101, and the display color resistance 22 is used to cover a plurality of pixel areas 1011, so that the light passing through each pixel area 1011 is colored light.
[0078] In addition, the display color resistance 22 is arranged between the data line 11 and the shielding electrode 31 in the display area 101.
[0079] In some embodiments, the display color resistance 22 comprises a plurality of second color resistances 221 arranged along the second direction N, and one second color resistance 221 covers a plurality of pixel areas 1011 arranged along the first direction M; wherein one second color resistance 221 is connected with one first color resistance 211 along the first direction M, and the connected first color resistance 211 and second color resistance 221 have the same color, and the colors of adjacent second color resistances 221 are different.
[0080] The second color resistance 221 can comprise a red color resistance, a green color resistance and a blue color resistance, and along the second direction N, a plurality of second color resistances 221 can be arranged in a cycle of red color resistance, green color resistance and blue color resistance in sequence, so as to realize the color display of a plurality of pixel areas 1011.
[0081] Correspondingly, since the colors of the connected first color resistance 211 and second color resistance 221 along the first direction M are the same, along the second direction N, the first color resistance 211 can also be arranged in a cycle of red color resistance, green color resistance and blue color resistance in sequence; it should be noted that the connected first color resistance 211 and second color resistance 221 along the first direction M can be integrally formed, that is, the preparation of the connected first color resistance 211 and second color resistance 221 is completed in the same process, thereby effectively reducing the process and reducing the process cost.

In addition, the spacer 21 in the non-display area 102 and the display color resist 22 in the display area 101 can be prepared in the same process, thereby effectively reducing the process and reducing the process cost.
[0083] In another embodiment of the present application, please refer to FIG. 4, FIG. 12 and FIG. 13, the color resist layer 20 can include a first color color resist, a second color color resist and a third color color resist, and the colors of the first color color resist, the second color color resist and the third color color resist are different from each other. For example, the first color color resist can be a red color resist, the second color color resist can be a green color resist, and the third color color resist can be a blue color resist.

Thus, the color display of the display panel can be realized.
[0085] In some embodiments, the spacer 21 includes one of a first color color resist, a second color color resist and a third color color resist. Similarly, the spacer 21 can be completed in the same process of the display color resist 22.
[0086] For example, when the spacer 21 is the first color color resist, the display panel can form the first color color resist in some pixel areas 1011 in the display area 101 and form the first color color resist in the non-display area 102 at the same time when the first color color resist is prepared.
