[0002] Electronic paper is a paper-like electronic display that combines the display characteristics of ordinary paper with those of a computer screen. It provides a display effect close to that of ordinary paper, reducing eye strain during reading.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0045] Please refer to 1 and Figure 2 In related technologies, the panel motherboard 1 needs to be cut along the cutting line 3 to obtain multiple small boards 2 of preset size. Each small board 2 includes a test terminal 4 and a test trace 5 is provided on the panel motherboard 1. The test trace 5 is connected to the test terminal 4, so that the multiple small boards 2 on the panel motherboard 1 can be tested for illumination. However, during the cutting process of the panel motherboard 1, the cutting line 3 passes through the test trace 5. After cutting, the test trace 5 will form a cross-section at the cutting surface. Since the test trace 5 is made of metal material, generally a single metal material, it is easy to generate static electricity, which will damage the components and traces in the small board 2 and affect the display effect.

[0046] Please refer to Figure 3 , Figure 4 as well as Figure 5 This invention provides a display panel, which includes a display area 101 and a non-display area 102 adjacent to the display area 101. The non-display area 102 includes an outer boundary 1021 on the side away from the display area 101.

[0047] The display panel also includes a metal terminal 11 and a first metal line segment 21; the metal terminal 11 is disposed in the non-display area 102; the first metal line segment 21 is disposed in the non-display area 102, one end of the first metal line segment 21 is connected to the metal terminal 11, and the other end of the first metal line segment 21 extends to the outer boundary 1021.

[0048] The first metal segment 21 includes a first sub-section 211 extending to the outer boundary 1021, and the first sub-section 211 contains a metal oxide.

[0049] In the implementation and application process, the embodiments of the present invention use metal oxide to prepare the first sub-part 211 connecting the first metal line segment 21 to the outer boundary 1021, thereby reducing the conductivity of the first sub-part 211, reducing the static electricity generated by the first sub-part 211, reducing the probability of the traces or devices in the display panel being damaged by static electricity, and improving the stability and display effect of the display panel.

[0050] Please continue to refer to Figure 3 , Figure 4 as well as Figure 5 The display panel provided in this embodiment of the invention includes a display area 101 and a non-display area 102 adjacent to the display area 101. The non-display area 102 surrounds the display area 101 and includes an outer boundary 1021 on the side away from the display area 101.

[0051] The display panel also includes driving circuits, display signal lines, and test traces 31 disposed in the display area 101 and the non-display area 102. For example, a pixel driving circuit is disposed in the display area 101, and a gate driving circuit is disposed in the non-display area 102. The display panel also includes bonding terminals disposed in the non-display area 102, a driving chip 33 connected to the bonding terminals, a flexible circuit board 34, and a metal terminal 11. The display signal lines are connected to the bonding terminals and are used to connect the driving chip 33, the flexible circuit board 34, and the driving circuit to transmit the signals on the driving chip 33 to the driving circuit to realize the display function of the display panel. In addition, the test traces 31 are used to connect to the metal terminal 11 to load test signals onto the metal terminal 11 during the manufacturing process of the display panel to perform a lamp test on the display panel.

[0052] In one embodiment, there can be multiple metal terminals 11, and the signals loaded in each metal terminal 11 can include scanning signals, switching signals, and common voltage signals, so that during the lamp lighting test, the corresponding signals such as scanning signals, switching signals, and common voltage signals can be transmitted to the driving circuits in the display panel through the metal terminals 11.

[0053] The display panel also includes a first metal line segment 21, which is connected to a metal terminal 11 and is used to input test signals to the metal terminal 11 during the manufacturing process of the display panel. The first metal line segment 21 is a residual line segment of the metal signal line after cutting.

[0054] One end of the first metal line segment 21 is connected to the metal terminal 11, and the other end of the first metal line segment 21 extends to the outer boundary 1021. The first metal line segment 21 includes a first sub-part 211 extending to the outer boundary 1021, and the material of the first sub-part 211 includes metal oxide. In this embodiment of the invention, by using metal oxide to prepare the part of the first metal line segment 21 connected to the outer boundary 1021, the cross-section of the first metal line segment 21 after cutting is a metal oxide cross-section, which can reduce the conductivity of the first sub-part 211, reduce the static electricity generated by the first sub-part 211, reduce the probability of the traces or devices in the display panel being damaged by static electricity, and improve the stability and display effect of the display panel.

[0055] In one embodiment of the present invention, please refer to Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The display panel includes a first side 1001 and a second side 1002 that are disposed opposite to each other, and the metal terminal 11, the driver chip 33 and the flexible circuit board 34 are all disposed on the first side 1001 of the display panel.

[0056] The non-display area 102 includes a fan-out area 1022 located on the first side 1001 and adjacent to the display area 101, and a bonding area 1023 located on the side of the fan-out area 1022 away from the display area 101. The bonding terminals are disposed in the bonding area 1023. The driver chip 33 and the flexible circuit board 34 are bonded and connected in the bonding area 1023. The display panel also includes a fan-out trace 35 connected to the driver chip 33 and extending into the fan-out area 1022. The fan-out trace 35 passes through the fan-out area 1022 and is connected to the signal traces in the display area 101, such as data lines, scan lines, etc., or to the signal traces in the non-display areas 102 on the left and right sides of the display area 101, such as clock signal lines, etc. The metal terminals 11 can be located in the bonding area 1023 and can be disposed on the left and right sides of the driver chip 33.

[0057] In this embodiment, a first metal segment 21 is disposed on a first side 1001 and connected to a metal terminal 11 and an outer boundary 1021 located on the first side 1001. The first metal segment 21 includes a first sub-part 211 extending to the outer boundary 1021, and the material of the first sub-part 211 includes a metal oxide.

[0058] In this embodiment, one end of the first sub-part 211 is connected to the metal terminal 11, and the other end of the first sub-part 211 extends to the outer boundary 1021 located on the first side 1001.

[0059] In this embodiment, the number of metal terminals 11 on the first side 1001 of the display panel can be multiple, and the multiple metal terminals 11 can be symmetrically located at opposite ends of the first side 1001. The connection method of the metal terminal 11 located at one end of the first side 1001 is used as an example for explanation.

[0060] The display panel also includes a second metal line segment 22 disposed on the second side 1002, and the second metal line segment 22 is connected to the outer boundary 1021 of the second side 1002. Specifically, the second metal line segment 22 includes a second sub-part 221 extending to the outer boundary 1021 of the second side 1002 and a third sub-part 222 connected to the side of the second sub-part 221 away from the outer boundary 1021.

[0061] The first metal segment 21 includes a first end extending to the outer boundary 1021 of the first side 1001, and the second metal segment 22 includes a second end extending to the outer boundary 1021 of the second side 1002. The first end and the second end are aligned along the direction from the first side 1001 to the second side 1002.

[0062] Specifically, the second sub-part 221 is aligned with the first sub-part 211 along the direction from the first side 1001 to the second side 1002, and the material of the second sub-part 221 is the same as that of the first sub-part 211, while the material of the third sub-part 222 is different from that of the first sub-part 211.

[0063] In one embodiment, the conductivity of the material of the first sub-part 211 is less than that of the material of the third sub-part 222, and the conductivity of the material of the second sub-part 221 is less than that of the material of the third sub-part 222. This can reduce the static electricity generated by the first sub-part 211 and the second sub-part 221 connected to the outer boundary 1021, reduce the probability of electrostatic damage to the internal components and traces of the display panel, and improve the yield and display effect of the display panel.

[0064] In one embodiment, the chemical stability of the material of the first sub-part 211 is greater than that of the material of the third sub-part 222, and the chemical stability of the material of the second sub-part 221 is greater than that of the material of the third sub-part 222. That is, the metallic inertness of the material of the first sub-part 211 and the metallic inertness of the material of the second sub-part 221 are greater than that of the material of the third sub-part 222. This can reduce the probability of moisture entering the interior of the display panel through the first sub-part 211 and the second sub-part 221, and reduce the probability of moisture entering the interior of the display panel through the first metal line segment 21, thereby further improving the yield and display effect of the display panel.

[0065] The materials of the first sub-part 211 and the second sub-part 221 may both include metal oxides, such as indium tin oxide, indium zinc oxide, or zinc oxide; the material of the third sub-part 222 may include elemental metals, such as copper.

[0066] It should be noted that the display panel includes a substrate and a gate layer, a source / drain layer and a pixel electrode layer disposed on the substrate. The first sub-part 211 and the second sub-part 221 may be located in the pixel electrode layer, while the third sub-part 222 may be located in the gate layer or the source / drain layer. When the second sub-part 221 and the third sub-part 222 are located in different film layers, they can be connected by vias.

[0067] In addition, the metal terminal 11 can be located in the gate layer or the source / drain layer, and the first sub-part 211 and the metal terminal 11 are located in different film layers. Therefore, the first sub-part 211 can also be connected to the metal terminal 11 through a via.

[0068] In one embodiment, a signal lead 36 is spaced between the metal terminal 11 and the outer boundary 1021 of the first side 1001, and the signal lead 36 can be disposed on the same layer as the metal terminal 11. The first sub-part 211 needs to cross the signal lead 36 and then connect to the metal terminal 11 through a via. The signal lead 36 may include a common voltage signal line.

[0069] Furthermore, the display panel also includes a functional signal line 32 disposed within the non-display area 102, and the functional signal line 32 is also electrically connected to the driving circuit; on the second side 1002 of the display panel, the spacing L between the second metal line segment 22 and the functional signal line 32 is greater than or equal to 30 micrometers, such as... Figure 6 As shown; since the second metal line segment 22 is suspended after the cutting process and is located in the panel trace or other device connection, the second metal line segment 22 is prone to accumulating static electricity, which can easily cause static damage to the adjacent trace. Therefore, in this embodiment of the invention, by increasing the distance between the second metal line segment 22 and the functional signal line 32, the probability of the functional signal line 32 being damaged is reduced, thereby further improving the yield and stability of the display panel.

[0070] Continuing from the above, in this embodiment of the invention, by using a metal oxide to prepare the first sub-part 211 connecting the first metal line segment 21 to the outer boundary 1021, the conductivity of the first sub-part 211 can be reduced, the static electricity generated by the first sub-part 211 can be reduced, and the probability of the traces or devices in the display panel being damaged by static electricity can be reduced. In addition, the fact that the first sub-part 211 is prepared using a metal oxide can also reduce the probability of moisture entering the interior of the display panel through the first metal line segment 21, thereby improving the stability and display effect of the display panel.

[0071] In another embodiment of the invention, please refer to Figure 7 , Figure 8 as well as Figure 9 The difference between this embodiment and the previous embodiment is that in this embodiment, the display panel includes a first metal line segment 21 disposed on the first side 1001, a second metal line segment 22 and a third metal line segment 23 disposed on the second side 1002, and a fourth metal line segment 24 disposed on the first side 1001.

[0072] One end of the first metal wire segment 21 is connected to the metal terminal 11, and the other end of the first metal wire segment 21 extends to the outer boundary 1021 of the first side 1001. The first metal wire segment 21 includes a first sub-part 211 extending to the outer boundary 1021, a fourth sub-part 212 connected to the metal terminal 11, and a fifth sub-part 213 connected between the first sub-part 211 and the fourth sub-part 212.

[0073] In one embodiment, the material of the first sub-part 211 is the same as that of the fourth sub-part 212. The conductivity of the material of the first sub-part 211 is less than that of the material of the fifth sub-part 213, and the chemical stability of the material of the first sub-part 211 is greater than that of the material of the fifth sub-part 213. Therefore, this embodiment of the invention can reduce the conductivity of the first sub-part 211 extending to the outer boundary 1021, reduce the static electricity generated by the first sub-part 211, lower the probability of electrostatic damage to traces or components in the display panel, and improve the stability and display effect of the display panel. Furthermore, this embodiment of the invention can also reduce the probability of moisture intruding into the interior of the display panel through the first metal line segment 21, further improving the yield rate and display effect of the display panel.

[0074] In one embodiment, the materials of the first sub-part 211 and the fourth sub-part 212 may include metal oxides, and the first sub-part 211 and the fourth sub-part 212 may be located in the pixel electrode layer. The material of the fifth sub-part 213 includes an elemental metal, and the fifth sub-part 213 may be located in the source / drain layer or the gate layer. When the first sub-part 211, the fourth sub-part 212 and the fifth sub-part 213 are located in different film layers, they can be connected by vias.

[0075] The two ends of the second metal segment 22 extend to the outer boundary 1021 of the second side 1002, and the second metal segment 22 includes a second sub-part 221 extending to the outer boundary 1021 and a third sub-part 222 connected to the side of the second sub-part 221 away from the outer boundary 1021; wherein the second sub-part 221 and the first sub-part 211 are aligned and disposed along the direction from the first side 1001 to the second side 1002.

[0076] In one embodiment, the material of the first sub-part 211 is the same as the material of the second sub-part 221, and the material of the third sub-part 222 can be the same as the material of the fifth sub-part 213. The conductivity of the material of the first sub-part 211 is less than that of the material of the third sub-part 222, and the chemical stability of the material of the first sub-part 211 is greater than that of the material of the third sub-part 222. Therefore, this embodiment of the invention can reduce the conductivity of the first sub-part 211 and the second sub-part 221 extending to the outer boundary 1021, reduce the static electricity generated by the first sub-part 211 and the second sub-part 221, reduce the probability of electrostatic damage to the traces or devices in the display panel, and improve the stability and display effect of the display panel. Furthermore, this embodiment of the invention can also reduce the probability of moisture intruding into the interior of the display panel through the first metal line segment 21, further improving the yield rate and display effect of the display panel.

[0077] In one embodiment, the materials of the first sub-part 211 and the second sub-part 221 may include metal oxides, and the first sub-part 211 and the second sub-part 221 may be located in the pixel electrode layer. The material of the third sub-part 222 includes an elemental metal, and the third sub-part 222 may be located in the source / drain layer or the gate layer. When the first sub-part 211, the second sub-part 221 and the third sub-part 222 are located in different film layers, they can be connected by vias.

[0078] Both ends of the third metal segment 23 extend to the outer boundary 1021 of the second side 1002, and the third metal segment 23 includes a sixth sub-part 231 and a seventh sub-part 232 extending to the outer boundary 1021 of the second side 1002. The sixth sub-part 231 is aligned with the first sub-part 211 along the direction from the first side 1001 to the second side 1002, and the seventh sub-part 232 is offset from the first sub-part 211 along the direction from the first side 1001 to the second side 1002.

[0079] In one embodiment, the material of the sixth sub-part 231 is the same as that of the first sub-part 211 and may be located in the pixel electrode layer; the material of the seventh sub-part 232 is the same as that of the first sub-part 211 and may be located in the pixel electrode layer, or the material of the seventh sub-part 232 is the same as that of the third sub-part 222 and may be located in the gate layer or the source / drain layer.

[0080] Both ends of the fourth metal segment 24 extend to the outer boundary 1021 of the first side 1001. The fourth metal segment 24 includes an eighth sub-part 241 and a ninth sub-part 242 extending to the outer boundary 1021 of the first side 1001. The eighth sub-part 241 and the seventh sub-part 232 are aligned along the direction from the first side 1001 to the second side 1002, and the ninth sub-part 242 and the seventh sub-part 232 are offset along the direction from the first side 1001 to the second side 1002.

[0081] In one embodiment, the material of the eighth sub-part 241 is the same as that of the first sub-part 211 and may be located in the pixel electrode layer; or the material of the eighth sub-part 241 is the same as that of the third sub-part 222 and may be located in the gate layer or the source / drain layer. The material of the ninth sub-part 242 is the same as that of the first sub-part 211 and may be located in the pixel electrode layer; or the material of the ninth sub-part 242 is the same as that of the third sub-part 222 and may be located in the gate layer or the source / drain layer.

[0082] It should be noted that since the second metal segment 22, the third metal segment 23, and the fourth metal segment 24 are not directly connected to the metal terminal 11, that is, they are not directly connected to the in-plane wiring, the ends of the second metal segment 22, the third metal segment 23, and the fourth metal segment 24 that connect to the outer boundary 1021 do not need to be made of metal oxide. However, the first metal segment 21 is directly connected to the metal terminal 11, so the end of the first metal segment 21 that connects to the outer boundary 1021 needs to be made of metal oxide to reduce the static electricity generated by the first metal segment 21 and reduce the probability of moisture entering the display panel through the first metal segment 21, thereby improving the stability and display effect of the display panel.

[0083] Continuing from the above, in this embodiment of the invention, by using a metal oxide to prepare the first sub-part 211 connecting the first metal line segment 21 to the outer boundary 1021, the conductivity of the first sub-part 211 can be reduced, the static electricity generated by the first sub-part 211 can be reduced, and the probability of the traces or devices in the display panel being damaged by static electricity can be reduced. In addition, the fact that the first sub-part 211 is prepared using a metal oxide can also reduce the probability of moisture entering the interior of the display panel through the first metal line segment 21, thereby improving the stability and display effect of the display panel.

[0084] It should be noted that in the display panel provided in the embodiments of the present invention, the number of the first metal segment 21, the second metal segment 22, the third metal segment 23 and the fourth metal segment 24 can all be multiple, and the structure and connection method of each first metal segment 21, each second metal segment 22, each third metal segment 23 and each fourth metal segment 24 can be set with reference to the above embodiments, and will not be repeated here.

[0085] In addition, embodiments of the present invention also provide a display panel motherboard, please refer to... Figure 10 , Figure 11 as well as Figure 12 The display panel motherboard 40 includes at least two daughterboards 41.

[0086] It should be noted that after the display panel mother board 40 undergoes a cutting process to separate at least two sub-boards 41, and then undergoes subsequent bonding and other processes to obtain the display panel as described in the above embodiment.

[0087] The sub-board 41 includes a metal terminal 11, and the display panel motherboard 40 includes multiple metal signal lines 20. The multiple metal signal lines 20 are connected to the metal terminal 11 on the sub-board 41, and the metal signal lines 20 include a first metal segment 21 connected to the metal terminal 11.

[0088] Furthermore, one end of the first metal segment 21 is connected to the metal terminal 11, and the other end of the first metal segment 21 is connected to the junction between two adjacent sub-boards 41. The first metal segment 21 includes a first sub-section 211 connected to the junction of two adjacent sub-boards 41, and the composition of the first sub-section 211 contains metal oxide.

[0089] It is understood that the display panel motherboard provided in the embodiments of the present invention includes a cutting line 12, which is located between two adjacent sub-boards 41, that is, the boundary between two adjacent sub-boards 41 is the cutting line 12, and one end of the first metal line segment 21 is connected to the metal terminal 11, and the other end of the first metal line segment 21 is connected to the boundary between two adjacent sub-boards 41.

[0090] In this embodiment of the invention, the material of the first sub-part 211 of the first metal line segment 21 connected to the metal terminal 11 in the metal signal line 20 is set as metal oxide. Therefore, after the display panel motherboard is cut along the cutting line 12, the cross-section of the first metal line segment 21 directly connected to the metal terminal 11 is a metal oxide cross-section, which can reduce the conductivity of the first sub-part 211, reduce the static electricity generated by the first sub-part 211, and reduce the probability of the traces or devices in the display panel being damaged by static electricity. In addition, the fact that the first sub-part 211 is made of metal oxide can also reduce the probability of moisture entering the interior of the display panel through the first metal line segment 21, thereby improving the stability and display effect of the display panel.

[0091] It should be noted that the display panel motherboard 40 may include multiple subboards 41 and transmission signal lines 210 and input terminals 50 disposed around the multiple subboards 41; the transmission signal lines 210 are connected to the input terminals 50 and are disposed around the multiple subboards 41, while the metal signal lines 20 are located between two adjacent rows of subboards 41, and the two ends of the metal signal lines 20 along the row direction are connected to the transmission signal lines 210, so as to realize that the test signal is transmitted from the input terminals 50 to each subboard 41.

[0092] It should be noted that there can be multiple metal signal lines 20 to transmit various test signals to each daughterboard 41, such as scan signals, switch signals, and common voltage signals.

[0093] In one embodiment of the present invention, please refer to Figure 10 and Figure 11 Between two adjacent sub-boards 41 along the column direction, the cutting line 12 is located between the two sub-boards 41, and the portion of the metal signal line 20 that is directly connected to the metal terminal 11 and overlaps with the cutting line 12 is made of metal oxide.

[0094] Specifically, after the display panel motherboard 40 is cut along the cutting line 12, the metal signal line 20 is cut into a first metal line segment 21 and a second metal line segment 22. The first metal line segment 21 is located within the same metal signal line 20 after cutting. Figure 11 The second metal segment 22 obtained in the sub-plate 41 on the upper middle side is located in Figure 11 In the lower sub-plate 41, a first metal line segment 21 is formed on the lower side of the same sub-plate 41, and a second metal line segment 22 is formed on the upper side of the sub-plate 41.

[0095] It is understandable that the materials and connection methods of the first metal segment 21 and the second metal segment 22 in the sub-board 41 are similar to those of the sub-board 41. Figure 3 The same applies to the embodiments shown, and will not be repeated here.

[0096] In two adjacent sub-plates 41 along the column direction, the first sub-part 211 of the first metal line segment 21 in the upper sub-plate 41 is connected to the second sub-part 221 of the second metal line segment 22 in the lower sub-plate 41.

[0097] In another embodiment of the present invention, please refer to Figure 10 and Figure 12 Between two adjacent sub-boards 41 along the column direction, the cutting line 12 is located between the two sub-boards 41, and the portion of the metal signal line 20 that is directly connected to the metal terminal 11 and overlaps with the cutting line 12 is made of metal oxide.

[0098] Specifically, after the display panel motherboard 40 is cut along the cutting line 12, the metal signal line 20 is cut into a first metal segment 21, a second metal segment 22, a third metal segment 23, and a fourth metal segment 24. After the same metal signal line 20 is cut, the first metal segment 21 and the fourth metal segment 24 are located at... Figure 11 In the upper middle sub-plate 41, the obtained second metal segment 22 and third metal segment 23 are located Figure 11In the lower sub-plate 41, a first metal line segment 21 and a fourth metal line segment 24 are formed on the lower side of the same sub-plate 41, and a second metal line segment 22 and a third metal line segment 23 are formed on the upper side of the sub-plate 41.

[0099] It is understandable that the materials and connection methods of the first metal segment 21, the second metal segment 22, the third metal segment 23, and the fourth metal segment 24 in the sub-board 41 are all the same as those of the first metal segment 21, the second metal segment 22, the third metal segment 23, and the fourth metal segment 24. Figure 7 The same applies to the embodiments shown, and will not be repeated here.

[0100] In two adjacent sub-plates 41 along the column direction, the first sub-part 211 of the first metal line segment 21 in the upper sub-plate 41 is connected to the second sub-part 221 of the second metal line segment 22 and the sixth sub-part 231 of the third metal line segment 23 in the lower sub-plate 41, and the eighth sub-part 241 of the fourth metal line segment 24 in the upper sub-plate 41 is connected to the seventh sub-part 232 of the third metal line segment 23 in the lower sub-plate 41.

[0101] Continuing from the above, after the metal signal lines 20 are cut, they are distributed on the upper and lower sub-boards 41, thus ensuring that metal line segments are distributed on both the upper and lower sides of the display panel obtained from the sub-boards 41; however, it should be noted that, please refer to... Figure 10 , Figure 13 as well as Figure 14 In the display panel motherboard 40, a plurality of subboards 41 include a row of edge subboards 411 located on the uppermost side of the display panel motherboard 40. Since the metal signal line 20 is only located on the lower side of the edge subboard 411, the metal line segment generated after cutting is also only located on the lower side of the edge subboard 411.

[0102] In one embodiment, such as Figure 13 As shown, the display panel obtained through the edge sub-board 411 is relative to Figure 3 Regarding the display panel shown, Figure 13 The display panel shown includes only the first metal segment 21 located on the first side 1001.

[0103] In another embodiment, such as Figure 14 As shown, the display panel obtained through the edge sub-board 411 is relative to Figure 7 Regarding the display panel shown, Figure 14 The display panel shown includes only the first metal segment 21 and the fourth metal segment 24 located on the first side 1001.

[0104] In summary, in this embodiment of the invention, the portion where the metal signal line 20 is directly connected to the metal terminal 11 and intersects with the cutting line 12 is made of metal oxide. This makes the first sub-part 211 of the first metal line segment 21 connected to the outer boundary 1021 made of metal oxide, thereby reducing the conductivity of the first sub-part 211, reducing the static electricity generated by the first sub-part 211, and lowering the probability of the traces or devices in the display panel being damaged by static electricity. In addition, the fact that the first sub-part 211 is made of metal oxide can also reduce the probability of moisture entering the interior of the display panel through the first metal line segment 21, thereby improving the stability and display effect of the display panel.

[0105] Furthermore, embodiments of the present invention also provide a display device, which includes a display panel as described in the above embodiments.
